Disclosed round sizes in Tokyo are heavily skewed toward a single large deal: Sakana AI raised $129M on 2025-11-20, dwarfing the next-largest disclosed rounds (Luup and FactBase at $28M on 2025-11-30 and 2025-11-25, and IVRy at $26M on 2025-11-09). At the low end, the smallest disclosed amount is $340K (SEEDER on 2025-11-08; also Cataris at $330K on 2025-10-30 and DriveX at $330K on 2025-10-10 are slightly above that floor).
The list spans 50 rows from 2025-09-24 (FormX) through 2025-11-30 (Luup), concentrating activity in late November 2025. Stage disclosure is also uneven: 15 of 50 entries show “undisclosed” amounts, while another 9 carry “Venture - Series Unknown.” Sector-wise, artificial intelligence appears repeatedly across entries (e.g., Sakana AI 2025-11-20 $129M; IVRy 2025-11-09 $26M; FormX 2025-09-24 undisclosed), suggesting an AI-forward funding pattern across stages.

Frequently asked
What’s the largest disclosed round in Tokyo on this page, and how does it compare to the rest of the disclosed amounts?
Sakana AI’s $129M (2025-11-20) is the only clearly dominant disclosed amount on the page; the next-largest disclosed rounds cluster far lower at $28M for Luup (2025-11-30) and FactBase (2025-11-25), with IVRy at $26M (2025-11-09).
Are there notable outliers at the small end, and where do they show up in the date range?
SEEDER’s $340K (2025-11-08) is the smallest disclosed amount shown. Several other “near-floor” disclosures sit around late October to mid-October, including Cataris at $330K (2025-10-30) and DriveX at $330K (2025-10-10).
How concentrated are deals in time—do most rounds land in a narrow window?
Rounds span 2025-09-24 to 2025-11-30, but multiple of the largest disclosed deals fall in late November 2025, including Sakana AI ($129M on 2025-11-20), Luup ($28M on 2025-11-30), and FactBase ($28M on 2025-11-25).
What share of entries keep the round size undisclosed versus giving a numeric amount?
15 of 50 entries list “undisclosed” amounts (e.g., BEFFY on 2025-11-28 and Enerbank Japan on 2025-11-25). Separately, 9 of 50 are categorized as “Venture - Series Unknown,” which doesn’t by itself indicate the amount but does show another layer of disclosure variation.
Does the page show a stage mix skew—particularly around Seed versus later rounds—among disclosed deals?
Disclosed Seed rounds include AI Mage ($1M on 2025-11-22), SEEDER ($340K on 2025-11-08), and StartPass ($1M on 2025-11-08). Later disclosed rounds appear as well—e.g., Series B includes Sakana AI ($129M on 2025-11-20) and Series C includes FactBase ($28M on 2025-11-25)—but the presence of “undisclosed” and “Venture - Series Unknown” entries limits how much can be inferred from stage labels alone.
Is there a sector cluster that appears across multiple entries (not just one company), and are its big rounds concentrated?
Artificial intelligence shows up repeatedly across the list, including Sakana AI ($129M on 2025-11-20), IVRy ($26M on 2025-11-09), and FormX (AI + Data, 2025-09-24 with $18M). The biggest disclosed AI-linked round is the Sakana AI deal, which stands apart from other disclosed AI-adjacent rounds like IVRy at $26M.
