What's the endgame? Based in Hiratsuka, Ark builds modular recirculating aquaculture systems (RAS) under the concept of creating "small oceans" on land. It plans to use the funds for technology and product development, fish farm construction, and hiring global talent.

How big is the round? The raise ranks in the 95th percentile of all-time Series A rounds in Japan's food sector, based on a sample of 109 deals. That places it among the largest early-stage food rounds the country has seen.

The signal: Land-based aquaculture is gaining policy tailwind in Japan, where the government's July 2026 "Japan Growth Strategy" named food tech one of 17 strategic sectors and singled out land-based farming. "What we call modular land-based aquaculture is a challenge toward the democratisation of the fishing industry," said chief executive officer Yosuke Kurihara (translated from Japanese). The round positions Ark to export domestic fishing technology into food-security markets across the Global South.
