Across the 11 most recent Japan health care entries, the largest disclosed round is Sound Wave Innovation’s $17M Series C on 2026-05-18, which stands well above the next-largest disclosed amounts ($8M by NovAccel on 2026-05-10 and $7M by Magic Shields on 2026-04-21). Several other disclosed rounds cluster in a mid-single-to-low double-digit band, while three companies have undisclosed funding (AndL on 2026-06-16; Instalimb on 2026-05-18; and LocationMind, Astena Holdings Co., all undisclosed on 2026-04-08 and 2026-04-02 respectively).
Geographically, Tokyo appears repeatedly: 7 of the 11 rows list Tokyo (including multiple Tokyo sub-areas like Toranomon and Tokyo, Tokyo), with the remaining entries in Nagoya (NAGARA), Hamamatsu (Magic Shields), and Tsuchiura (NovAccel). Temporally, the displayed rounds concentrate tightly between 2026-04-02 and 2026-06-16, with the single older datapoint at HekaBio on 2021-01-29.

Frequently asked
What stands out on deal size among the most recent Japan health care rounds, and how does it compare to other disclosed amounts?
Sound Wave Innovation’s $17M Series C on 2026-05-18 is the largest disclosed amount in the 11-row view, exceeding NovAccel’s $8M (2026-05-10) and Magic Shields’ $7M (2026-04-21) and sitting above the rest of the disclosed amounts, which include $3M (EEFUL, 2026-04-06) and $2M (IWG, 2026-06-02).
Is there a city or location clustering in this list?
Tokyo dominates the geography: 7 of 11 rows list Tokyo (for example, AndL 2026-06-16; IWG 2026-06-02; EEFUL 2026-04-06; and Astena Holdings Co. 2026-04-02). The non-Tokyo entries are NAGARA in Nagoya (2026-05-25), Magic Shields in Hamamatsu (2026-04-21), and NovAccel in Tsuchiura (2026-05-10).
Which entries fall inside the most recent ~90-day window shown here?
Using the latest row date of 2026-06-16, every other row from 2026-06-02 back through 2026-04-08 is within roughly 90 days: IWG (2026-06-02, $2M), NAGARA (2026-05-25, $200K), Instalimb (2026-05-18, undisclosed), Sound Wave Innovation (2026-05-18, $17M), NovAccel (2026-05-10, $8M), Magic Shields (2026-04-21, $7M), and LocationMind (2026-04-08, undisclosed). The remaining rows are EEFUL (2026-04-06), Astena Holdings Co. (2026-04-02), and HekaBio (2021-01-29).
What stage mix appears most often, and how much of the list is non-disclosed or unknown stage?
Stage is frequently unspecified: 4 of 11 rows are labeled “Series Unknown” (NAGARA 2026-05-25; Instalimb 2026-05-18; LocationMind 2026-04-08; Astena Holdings Co. 2026-04-02), and 3 of 11 rows have an “undisclosed” amount (AndL 2026-06-16; Instalimb 2026-05-18; LocationMind 2026-04-08; Astena Holdings Co. 2026-04-02). Disclosed stages still show concentration at Seed and B/C: Seed appears on IWG (2026-06-02, $2M) and NovAccel (2026-05-10, $8M) plus two entries with non-disclosed/unknown amounts (AndL, undisclosed; and HekaBio is the older Series B at $4M on 2021-01-29).
Are there outliers in disclosed amounts within this segment?
Yes. In addition to Sound Wave Innovation’s $17M on 2026-05-18, the smallest disclosed amount is NAGARA’s $200K on 2026-05-25, which is far below the next-low disclosed figures like EEFUL’s $3M (2026-04-06) and IWG’s $2M (2026-06-02). That spread suggests a wide funding range across otherwise similarly dated 2026 rounds.
