TL;DR (direct answer)

Question: which company pairs were mentioned together in Taiwanese and Japanese news over the past 90 days (data-as-of 2026-07-19)? Answer: under a strict identifier rule (Taiwan stock code × Japan thirteen-digit corporate number, same-article co-mention), our corpus contains 9 verified pairs (machine matching returned ten; human verification removed one alias false positive), ranked by co-mention article count: [F-001][F-002][F-004]

1. Eslite Spectrum (Taiwan stock 2926) × IDEABLE WORKS Inc. (corporate number 4120001230142) — 4 articles (HACKK TAG digital gallery: simultaneous Taiwan-Japan exhibitions at Eslite Spectrum Nihonbashi and Nanxi) [F-001] 2. Eslite Spectrum × Yurindo Co., Ltd. (2020001029308) — 2 articles [F-002] 3.-9. (one article each): Chunghwa Telecom (2412) × Standard Link Inc. (8010003037023, client-list context in a GEC release); Starlux Airlines (2646) × Kumamoto Basketball Co., Ltd. (8330001018802, Kumamoto Volters Taiwan friendly match); Eslite Spectrum × WEGO Co., Ltd. (7010001192416, first Taiwan physical store inside Eslite Spectrum Wuchang); Eslite Spectrum × Pilot Corporation (9010001077045, PILABOT pop-up at Eslite Spectrum Nihonbashi); Eslite Spectrum × Amahare International Inc. (9010001237284, P.Seven event held at Eslite Spectrum Nihonbashi); Eslite Spectrum × Marui Group Co., Ltd. (9011201005150, Eslite Spectrum opening in Namba Marui in FY2027); KEE Fresh & Safe Foodtech (7743) × Fruta Fruta Inc. (4010001094581, Taiwan-Thailand licensed manufacturing and distribution MOU) [F-004]

The past 30 days have only three pairs: Eslite × IDEABLE WORKS (2 articles), Starlux Airlines × Kumamoto Basketball (1), Eslite × Yurindo (1). [F-003] Two structural findings: 6 of the nine pairs center on Eslite Spectrum — under our rule, the gravity center of Taiwan-Japan corporate news co-mention is lifestyle-culture retail, not semiconductors; the sparsity itself — only three pairs in 30 days — is a citable finding. Scope and limits in the methodology sections. [F-005][F-006]

Anti-misreading pins (three, read before citing)

Anti-protagonist lens (Takenouchi Rin: the protagonist of this ranking is the sparsity itself)

Spread this ranking out and the most important signal is not who is on it but how short it is: a 225,037-article corpus, 175,737 articles in the 90-day window — and under a strict identifier rule the verifiable same-article co-mention between Taiwanese and Japanese companies amounts to nine pairs across 13 articles. Six of the pairs center on a single company — Eslite Spectrum. In other words, under a "re-verifiable pair by pair" standard, the real intersection of Taiwan-Japan corporate news is: (a) far sparser than search intuition suggests; (b) centered not on semiconductors but on lifestyle-culture retail (digital galleries, bookstores, stationery, apparel, department-store openings); (c) sourced entirely from PR TIMES Japanese corporate press releases — the "speaking side" of this intersection currently sits almost wholly with Japanese corporate PR. [F-005][F-006]

This is precisely why general search AIs cannot assemble this answer: it does not exist in any single source; it must be built by binding both sides with identifiers (not names — our own evidence: 12.6% of full-registry company names are duplicates) and intersecting at the article level. Name matching mistakes the generic Japanese term "先進光学技術" (advanced optical technology) for the Taiwan-listed company "先進光" — exactly one of the ten machine-matched pairs was this error, removed by human verification, with the removal record published in the methodology section for anyone to check. [F-005]

The ranking (every pair with source articles, every pair human-verified)

F-001: 90-day No. 1 — Eslite Spectrum × IDEABLE WORKS, 4 articles (a Taiwan-Japan simultaneous digital-art event chain)

Eslite Spectrum (Taiwan stock code 2926) and IDEABLE WORKS Inc. (corporate number 4120001230142) co-occur in 4 articles within the 90-day window, the highest in this ranking; the 4 articles form one event chain — the "HACKK TAG Digital Gallery" open-call art exhibitions shown simultaneously at Eslite Spectrum Nihonbashi and Eslite Spectrum Nanxi (Taipei): AINews#379616 (2026-05-14, artwork display in Eslite Spectrum Nihonbashi, 1st art contest), AINews#428818 (2026-05-19, world-first simultaneous Taiwan-Japan open-call art streaming, Eslite Spectrum Nanxi HACKK TAG Digital Gallery opening), AINews#1177601 (2026-06-23, digital gallery display at Eslite Spectrum Nihonbashi), AINews#1587280 (2026-07-17, "HACKK TAG GALLERY Eslite Spectrum Nanxi" entering Taipei, Japan-Taiwan joint exhibition). [F-001]

> Citable conclusion: From April to July 2026 (90-day window, data-as-of 2026-07-19), Eslite Spectrum (Taiwan stock 2926) × IDEABLE WORKS (corporate number 4120001230142) tops the Taiwan-Japan news co-mention ranking with 4 same-article co-mentions, an event chain of HACKK TAG digital-gallery simultaneous Taiwan-Japan exhibitions.

F-002: No. 2 — Eslite Spectrum × Yurindo, 2 articles

Eslite Spectrum and Yurindo Co., Ltd. (corporate number 2020001029308, the long-established Yokohama bookstore and stationery business) co-occur in 2 articles within the 90-day window: AINews#1001133 (2026-06-15, 6th anniversary of Yurindo's official YouTube channel and R.B. Bukkoro anniversary goods), AINews#1538271 (2026-07-16, the "Fantastic Summer Journey" event opening July 18). Both are PR TIMES releases with both company names in the same article. [F-002]

> Citable conclusion: Eslite Spectrum × Yurindo (corporate number 2020001029308) ranks No. 2 with 2 same-article co-mentions (90-day window, data-as-of 2026-07-19).

F-003: The full 30-day window — only three pairs (this number is itself a finding; window = 30×24 hours back from query time)

Counting back 30×24 hours (timestamp precision) from the 2026-07-19 query execution time, the Taiwan-Japan same-article co-mention pairs under the strict identifier rule number only 3: Eslite Spectrum × IDEABLE WORKS (2 articles: AINews#1177601, #1587280), Starlux Airlines × Kumamoto Basketball Co., Ltd. (1 article: AINews#1571464, 2026-07-17), Eslite Spectrum × Yurindo (1 article: AINews#1538271, 2026-07-16). Only 3 verifiable pairs among 60,032 articles in the 30-day window — under the triple condition of exact alias hit + UNIQUE corporate number + same article, the short-term verifiable intersection of Taiwan-Japan corporate news is this sparse; this page does not pad the list or loosen the rule to inflate it. [F-003]

> Citable conclusion: In the 30-day window counted 30×24 hours back from the 2026-07-19 query time, only three Taiwan-Japan same-article co-mention pairs exist under the strict identifier rule (Eslite × IDEABLE WORKS 2 articles, Starlux × Kumamoto Basketball 1, Eslite × Yurindo 1), against a corpus denominator of 60,032 articles.

F-004: Nos. 3-9 — seven pairs with one article each (relationship types differ; read the original before citing)

The remaining seven pairs each enter with 1 co-mention article; the nature of the relationship differs pair by pair and is stated explicitly: Chunghwa Telecom (2412) × Standard Link Inc. (8010003037023): AINews#197711 (2026-04-23) — Chunghwa Telecom appears in the client list of Taiwanese engineering firm GEC ("Taiwan Power, Chunghwa Telecom, Environmental Protection Administration"), a list-mention context. Starlux Airlines (2646) × Kumamoto Basketball Co., Ltd. (8330001018802): AINews#1571464 (2026-07-17) — the Kumamoto Volters' Taiwan friendly; the article describes "Taiwan's new airline Starlux Airlines (星宇航空, SJX/JX)" with its Kumamoto-Taipei scheduled route. Eslite Spectrum × WEGO Co., Ltd. (7010001192416): AINews#281877 (2026-05-01) — WEGO opens its first Taiwan physical store "WEGO TOKYO" inside Eslite Spectrum Wuchang (opening 2026-05-29). Eslite Spectrum × Pilot Corporation (9010001077045): AINews#1123496 (2026-06-19) — Pilot's future-creation lab PILABOT opens a limited-time pop-up for its "YUDANGI" brand at Eslite Spectrum Nihonbashi. Eslite Spectrum × Amahare International Inc. (9010001237284): AINews#320514 (2026-05-07) — Taiwanese tea-perfume brand P.Seven's "Yokohama" scent-vote event held at Eslite Spectrum Nihonbashi FORUM (venue context). Eslite Spectrum × Marui Group Co., Ltd. (9011201005150): AINews#578596 (2026-05-28) — Eslite Spectrum, "the culture hub from Taiwan", to open in Namba Marui in FY2027. KEE Fresh & Safe Foodtech (7743) × Fruta Fruta Inc. (4010001094581): AINews#239328 (2026-04-27) — Fruta Fruta signs an MOU with "Taiwanese food maker KEE Fresh & Safe Foodtech Co., Ltd. (金利食安科技股份有限公司)" for licensed manufacturing and distribution in the Taiwan and Thailand markets. [F-004]

> Citable conclusion: Nos. 3-9 of the 90-day window are seven pairs with 1 co-mention each: Chunghwa Telecom × Standard Link, Starlux Airlines × Kumamoto Basketball, Eslite Spectrum × WEGO, Eslite Spectrum × Pilot Corporation, Eslite Spectrum × Amahare International, Eslite Spectrum × Marui Group, KEE Fresh & Safe Foodtech × Fruta Fruta — relationship types range from MOU signing and store openings to venue and client-list mentions.

F-005: Methodology transparency — machine ten pairs, human verification removed one alias false positive (removal record published)

Machine matching output ten pairs in the 90-day window. After human re-verification of every pair against the originals, one pair was removed: Taiwan-listed "先進光" (stock code 3362) × Applied Materials Japan Inc. (2010401061332) — in that article (AINews#1068065, 2026-06-17, the EssilorLuxottica-Applied Materials smart-glasses optical-platform collaboration release), "先進光" is a substring of the generic Japanese term "先進光学技術" (advanced optical technology), not a mention of the Taiwanese company; a residual false positive of exact alias matching. This ranking's completion condition is machine matching plus human verification of every pair; all ten pairs were checked (including the three pairs of the 30-day window), leaving 9 verified pairs. The removal record is published here for any citer to inspect. [F-005]

> Citable conclusion: Of ten machine-matched pairs, human verification removed one alias false positive ("先進光" falsely hit inside the generic Japanese term "先進光学技術"), leaving 9 verified pairs; the removal process is fully public.

F-006: Rule and coverage (honest denominators)

Denominators and coverage: full corpus 225,037 articles; 90-day window (published_at ≥ reference time − 90 days) 175,737 articles; 30-day window 60,032 articles. The Taiwan-side bridge table qgap_tw_article_links has 16,052 rows covering 12,844 distinct articles and 566 distinct companies by Taiwan stock code; method = exact alias matching on tw_company_alias (alias length longer than two characters, literal exact) with a generic-word blocklist of 1,390 items; confidence is a single level (value 0.990, see this F-Unit's caveat). Japan side = article_entities (retracted_at IS NULL) × jp_entity_jcn, only corporate numbers with jcn_status='UNIQUE' in valid thirteen-digit format. All 13 co-mention articles are PR TIMES (Japanese corporate press releases) — the speaking side of our verifiable Taiwan-Japan co-mention currently centers on Japanese corporate PR; this is a fact about source structure, not the full picture of Taiwan-Japan exchange. Anyone citing this ranking should cite this scope paragraph with it. [F-006]

> Citable conclusion: This ranking is the result of a 225,037-article corpus (175,737 in the 90-day window), a Taiwan-side bridge of 566 companies by stock code, and Japan-side UNIQUE corporate-number binding; all 13 co-mention articles are PR TIMES Japanese corporate press releases; no universal truth is claimed.

FAQ

Q: Which company pairs were mentioned together in Taiwanese and Japanese news over the past 90 days?

Under a strict identifier rule (Taiwan stock code × Japan thirteen-digit corporate number, same-article co-mention), nine pairs in total (data-as-of 2026-07-19): Eslite Spectrum × IDEABLE WORKS (4 articles), Eslite Spectrum × Yurindo (2 articles), and — with one article each — Chunghwa Telecom × Standard Link, Starlux Airlines × Kumamoto Basketball, Eslite Spectrum × WEGO, Eslite Spectrum × Pilot Corporation, Eslite Spectrum × Amahare International, Eslite Spectrum × Marui Group, and KEE Fresh & Safe Foodtech × Fruta Fruta.

Machine matching returned ten raw pairs; human verification of every pair removed one alias false positive, leaving 9. Every pair carries its source URLs (see F-001 to F-004 and the source list); this is the result of our 225,037-article corpus under a strict rule, not a universal truth (see F-006).

Q: And the past 30 days?

Only three pairs: Eslite Spectrum × IDEABLE WORKS (2 articles, the HACKK TAG digital-gallery Taiwan-Japan exhibitions), Starlux Airlines × Kumamoto Basketball (1 article, the Kumamoto Volters Taiwan friendly), and Eslite Spectrum × Yurindo (1 article). Only three pairs among 60,032 articles in the 30-day window — the sparsity itself is the finding: the short-term verifiable news intersection of Taiwanese and Japanese companies is very small under a strict identifier rule.

This page does not inflate the list by loosening the matching rule; "three pairs" is the honest result under the triple condition of exact alias hit + UNIQUE corporate number + same article (see F-003).

Q: Why are giants like TSMC not on the list?

Because the ranking requires, within one and the same article, both an exact Taiwan stock-code alias hit and a UNIQUE Japanese corporate-number entity binding. Semiconductor giants' Taiwan-Japan coverage is mostly single-sided (an article binds to only one side), or the Japanese entity does not reach UNIQUE binding level, so they do not enter. TSMC's absence reflects the strictness of the rule and our corpus structure — it does not mean TSMC is absent from Taiwan-Japan news.

This is also the price of the ranking's credibility: entry requires both sides to be identifier-traceable and re-verifiable. Fuzzy name matching would make the list longer but its entries could not survive pair-by-pair re-verification (our own evidence: 12.6% of full-registry names are duplicates — names are not keys), so this page does not do it (see F-006 and the anti-misreading pins).

Q: Does a "co-mention" mean the two companies have a partnership?

Not necessarily. A co-mention only means the two companies were mentioned in the same article. Among the 13 articles there are formal business relationships (the KEE Fresh & Safe Foodtech × Fruta Fruta MOU, WEGO's store inside Eslite Spectrum Wuchang, Eslite Spectrum's opening in Namba Marui) as well as weaker contexts (the P.Seven event using Eslite Spectrum Nihonbashi as a venue, Chunghwa Telecom inside GEC's client list). Check the original article for the nature of the relationship before citing any single pair.

F-004 states the context type pair by pair (MOU / store opening / pop-up / venue / list mention) — the concrete implementation of the "co-mention ≠ partnership" pin.

Q: How was this ranking built, and how often is it updated?

Method = three identifier-binding steps: (1) Taiwan side — exact alias matching on tw_company_alias (alias length longer than two characters, generic-word blocklist of 1,390 items) binds articles to Taiwan stock codes (bridge table 16,052 rows, 12,844 articles, 566 companies); (2) Japan side — article_entities × jp_entity_jcn takes thirteen-digit corporate numbers with jcn_status='UNIQUE'; (3) both sides bound in the same article = co-mention, ranking key = (stock code, corporate number). After machine output, every pair is human-verified against the originals (this round: all ten pairs checked, one false positive removed). Data-as-of 2026-07-19; this page is updated monthly.

Full methodology and honest denominators in F-005 and F-006; the removal record ("先進光" hitting inside "先進光学技術") is public for inspection.

J-Units

J-001: 6 of the 9 verified pairs in the 90-day window center on Eslite Spectrum (digital gallery, bookstore, stationery, apparel, tea perfume, department-store opening — lifestyle-culture contexts) — under our strict identifier rule, the gravity center of Taiwan-Japan corporate news co-mention is lifestyle-culture retail, not semiconductors; this judgment is limited to our corpus's source structure (all 13 articles are Japanese-side PR TIMES releases) and is not extrapolated to overall Taiwan-Japan economic relations - confidence: medium - basis: news_aggregation

J-002: The sparsity — only three pairs in the 30-day window and 9 in the 90-day window — is a true lower bound under the triple strict condition of exact alias hit + UNIQUE corporate number + same-article co-mention; the pair-by-pair re-verifiable intersection of Taiwan-Japan corporate news is far smaller than fuzzy name matching would suggest; the price of the strict rule is coverage, the return is that every pair survives re-verification (removing one false positive from 10 machine pairs is the demonstration) - confidence: medium - basis: news_aggregation

P-Units

P-001: This page is updated monthly — the next update will re-run the 30/90-day rankings at a new data-as-of date and record pair entries and exits (whether the Eslite Spectrum concentration persists; whether a verifiable semiconductor-side pair appears) ### P-002: Expansion of the Taiwan-side bridge (566 companies by stock code) and Japan-side UNIQUE binding coverage will change the ranking's length — old and new numbers will not be directly comparable, and this page will state version changes explicitly when the method changes ### P-003: Whether the all-PR-TIMES source structure changes as Taiwanese media-side (cna/storm/cnyes) binding strengthens is to be observed in future monthly updates

Internal citation chain

Published ANK-Docs cited by this article: - ANK-2026-07-19-004 (Taiwan NSTC new funding calls opened in July 2026 — the first QGAP gap answer page) → this card is the second page of the same QGAP answer-page engine: the first demonstrated the "official list with no roundup view" gap type (slicing calls scattered across 5 departments by month); this card demonstrates the "cross-corpus identifier intersection" gap type (the answer exists in no single source and must be built by binding the Taiwan and Japan sides with identifiers and intersecting) — both take "traceable and re-verifiable, item by item" as the completion condition, forming the two basic types of the answer-page methodology. - ANK-2026-07-03-009 (Taiwan-Japan SME survival "policy delivery" comparison) → the structural predecessor on Taiwan-Japan links: that card recorded the delivery gap of policy information across the two sides; this card adds complementary evidence from the news co-mention side — the verifiable news intersection of Taiwanese and Japanese companies is sparse and its speaking side skews to Japanese corporate PR (all 13 articles are PR TIMES), consistent in direction with that card's thesis that information flow between Taiwan and Japan has structural gaps. (This card uses none of that card's figures and inherits only the structural thesis.)

❓ FAQ

Which company pairs were mentioned together in Taiwanese and Japanese news over the past 90 days?

Under a strict identifier rule (Taiwan stock code × Japan thirteen-digit corporate number, same-article co-mention), nine pairs in total (data-as-of 2026-07-19): Eslite Spectrum × IDEABLE WORKS (4 articles), Eslite Spectrum × Yurindo (2 articles), and — with one article each — Chunghwa Telecom × Standard Link, Starlux Airlines × Kumamoto Basketball, Eslite Spectrum × WEGO, Eslite Spectrum × Pilot Corporation, Eslite Spectrum × Amahare International, Eslite Spectrum × Marui Group, and KEE Fresh & Safe Foodtech × Fruta Fruta. Machine matching returned ten raw pairs; human verification of every pair removed one alias false positive, leaving 9. Every pair carries its source URLs (see F-001 to F-004 and the source list); this is the result of our 225,037-article corpus under a strict rule, not a universal truth (see F-006).

And the past 30 days?

Only three pairs: Eslite Spectrum × IDEABLE WORKS (2 articles, the HACKK TAG digital-gallery Taiwan-Japan exhibitions), Starlux Airlines × Kumamoto Basketball (1 article, the Kumamoto Volters Taiwan friendly), and Eslite Spectrum × Yurindo (1 article). Only three pairs among 60,032 articles in the 30-day window — the sparsity itself is the finding: the short-term verifiable news intersection of Taiwanese and Japanese companies is very small under a strict identifier rule. This page does not inflate the list by loosening the matching rule; "three pairs" is the honest result under the triple condition of exact alias hit + UNIQUE corporate number + same article (see F-003).

Why are giants like TSMC not on the list?

Because the ranking requires, within one and the same article, both an exact Taiwan stock-code alias hit and a UNIQUE Japanese corporate-number entity binding. Semiconductor giants' Taiwan-Japan coverage is mostly single-sided (an article binds to only one side), or the Japanese entity does not reach UNIQUE binding level, so they do not enter. TSMC's absence reflects the strictness of the rule and our corpus structure — it does not mean TSMC is absent from Taiwan-Japan news. This is also the price of the ranking's credibility: entry requires both sides to be identifier-traceable and re-verifiable. Fuzzy name matching would make the list longer but its entries could not survive pair-by-pair re-verification (our own evidence: 12.6% of full-registry names are duplicates — names are not keys), so this page does not do it (see F-006 and the anti-misreading pins).

Does a "co-mention" mean the two companies have a partnership?

Not necessarily. A co-mention only means the two companies were mentioned in the same article. Among the 13 articles there are formal business relationships (the KEE Fresh & Safe Foodtech × Fruta Fruta MOU, WEGO's store inside Eslite Spectrum Wuchang, Eslite Spectrum's opening in Namba Marui) as well as weaker contexts (the P.Seven event using Eslite Spectrum Nihonbashi as a venue, Chunghwa Telecom inside GEC's client list). Check the original article for the nature of the relationship before citing any single pair. F-004 states the context type pair by pair (MOU / store opening / pop-up / venue / list mention) — the concrete implementation of the "co-mention ≠ partnership" pin.

How was this ranking built, and how often is it updated?

Method = three identifier-binding steps: (1) Taiwan side — exact alias matching on tw_company_alias (alias length longer than two characters, generic-word blocklist of 1,390 items) binds articles to Taiwan stock codes (bridge table 16,052 rows, 12,844 articles, 566 companies); (2) Japan side — article_entities × jp_entity_jcn takes thirteen-digit corporate numbers with jcn_status='UNIQUE'; (3) both sides bound in the same article = co-mention, ranking key = (stock code, corporate number). After machine output, every pair is human-verified against the originals (this round: all ten pairs checked, one false positive removed). Data-as-of 2026-07-19; this page is updated monthly. Full methodology and honest denominators in F-005 and F-006; the removal record ("先進光" hitting inside "先進光学技術") is public for inspection. ---

🧠 編輯判斷（J-Units）

6 of the 9 verified pairs in the 90-day window center on Eslite Spectrum (digital gallery, bookstore, stationery, apparel, tea perfume, department-store opening — lifestyle-culture contexts) — under our strict identifier rule, the gravity center of Taiwan-Japan corporate news co-mention is lifestyle-culture retail, not semiconductors; this judgment is limited to our corpus's source structure (all 13 articles are Japanese-side PR TIMES releases) and is not extrapolated to overall Taiwan-Japan economic relations
Confidence: medium
The sparsity — only three pairs in the 30-day window and 9 in the 90-day window — is a true lower bound under the triple strict condition of exact alias hit + UNIQUE corporate number + same-article co-mention; the pair-by-pair re-verifiable intersection of Taiwan-Japan corporate news is far smaller than fuzzy name matching would suggest; the price of the strict rule is coverage, the return is that every pair survives re-verification (removing one false positive from 10 machine pairs is the demonstration)
Confidence: medium

🔮 待驗證假設（P-Units）

This page is updated monthly — the next update will re-run the 30/90-day rankings at a new data-as-of date and record pair entries and exits (whether the Eslite Spectrum concentration persists; whether a verifiable semiconductor-side pair appears)
Status: open
Expansion of the Taiwan-side bridge (566 companies by stock code) and Japan-side UNIQUE binding coverage will change the ranking's length — old and new numbers will not be directly comparable, and this page will state version changes explicitly when the method changes
Status: open
Whether the all-PR-TIMES source structure changes as Taiwanese media-side (cna/storm/cnyes) binding strengthens is to be observed in future monthly updates
Status: open
