Across the 19 most recent Japan Series A rounds shown, the largest disclosed amount is Turing’s $63M (2025-11-19), which sits well above the rest: the next-largest disclosed rounds are $15M (Tailor, 2025-11-20) and $14M (Nanofiber Quantum Technologies, 2025-09-24), while many entries cluster in the $1M–$10M range (for example, Nichietsu at $1M on 2025-10-29 and ZIRITZ at $5M on 2025-11-10). The list is also tightly time-bunched: the newest entry is Creator’s X on 2025-11-27, and 13 of the 19 rounds land between 2025-11-10 and 2025-11-20, with Tokyo appearing repeatedly across unrelated categories (Creator’s X, Tailor, ZIRITZ, HelloBoss, Nanofiber Quantum Technologies, and others). Sector-wise, AI shows up as a recurring theme across multiple companies (Creator’s X, Turing, HelloBoss, ZIRITZ, Forward, CROSS SYNC, Zen Intelligence, and Nanofiber Quantum Technologies). Finally, disclosures are incomplete for a substantial share: 4 of the 19 rounds list the amount as undisclosed (Atlas Associates 2025-11-26; HelloBoss 2025-11-18; HIKE 2025-10-03; EISHIN 2025-09-28), which limits comparisons to only the disclosed amounts.

Frequently asked
Which disclosed round is the clear size outlier in these Japan Series A entries?
Turing’s $63M on 2025-11-19 is the largest disclosed round, and it dwarfs the next-largest disclosed amounts ($15M for Tailor on 2025-11-20 and $14M for Nanofiber Quantum Technologies on 2025-09-24). Most other disclosed entries fall closer to the single-digit millions (for example, ZIRITZ at $5M on 2025-11-10 and Digital Securities Preparatory at $2M on 2025-09-28).
How concentrated are these rounds in time, based on the most recent rows shown?
The 19 rounds run from 2025-09-21 (Samansa) to 2025-11-27 (Creator’s X). Within that window, there’s heavy clustering in mid-November: 13 of the 19 rounds fall between 2025-11-10 and 2025-11-20 (including ZIRITZ 2025-11-10, Forward 2025-11-09, and Turing 2025-11-19).
Are any cities over-represented across these Series A companies?
Tokyo appears repeatedly as a base location across otherwise varied categories (Tailor 2025-11-20, ZIRITZ 2025-11-10, HelloBoss 2025-11-18, Digital Securities Preparatory 2025-09-28, and EISHIN 2025-09-28). Other city-level mentions are less frequent, such as Shibuya (Experisus on 2025-10-10 and Zeal Boxing Fitness on 2025-10-05) and Yokohama-Shi (Nichietsu on 2025-10-29).
Does one sector theme recur more often than others across this list?
Artificial Intelligence (AI) is a recurring thread across multiple companies: Creator’s X (Animation, AI) on 2025-11-27, Turing on 2025-11-19, HelloBoss on 2025-11-18, ZIRITZ on 2025-11-10, Forward on 2025-11-09, CROSS SYNC on 2025-10-07, Zen Intelligence on 2025-09-25, and Nanofiber Quantum Technologies (Quantum + hardware with an AI-adjacent profile) on 2025-09-24. The concentration is strong enough to shape how the list’s themes read, even though other sectors vary widely company-to-company.
How much of the dataset is hard to compare due to undisclosed round sizes?
4 of the 19 rows are marked undisclosed (Atlas Associates 2025-11-26, HelloBoss 2025-11-18, HIKE 2025-10-03, and EISHIN 2025-09-28). That means outlier checks and comparisons rely on the remaining 15 disclosed amounts rather than the full set of 19.
Are there any notably small disclosed rounds that sit at the bottom of the disclosed range?
The smallest disclosed amount is $1M, appearing in two entries: Nichietsu on 2025-10-29 ($1M) and xxxxnese on 2025-09-22 ($1M). These are at the low end compared with the top disclosed rounds like Turing’s $63M (2025-11-19) and Tailor’s $15M (2025-11-20).
