Osaka-based Light Touch Technology (LTT) has raised ¥500 million ($3M) in a Series B extension round to advance its non-invasive, MIR laser-based blood glucose sensor toward clinical trials and regulatory approval.

Japanese fusion startup Helical Fusion has raised $17M in its Series B first close, advancing its Helix Program to bring demonstration device Helix HARUKA online around 2030.

Qubitcore, a Japanese quantum computing startup, has raised $9.6 million in seed funding to advance its ion-trap quantum computer technology — an approach known for low error rates and long qubit coherence times.

Almure, a Tokyo-based startup founded in January 2026, has raised $1.25M in seed funding to develop confidential computing infrastructure for AI agents — aiming to secure sensitive enterprise data even while it is being processed.

Photo electron Soul, a Nagoya University-based startup developing semiconductor photocathodes, has raised approximately 900 million yen ($5.6 million). The funding will support mass production of its electron beam generation system, which simultaneously achieves the narrow beam and high current needed to inspect increasingly miniaturized and multi-layered semiconductor chips at speed.

LINK-US, a Japanese startup with a patented ultrasonic compound vibration technology for metal bonding, has raised 620 million yen (approximately $3.9 million) in a Series C extension round. The proceeds will fund development of a next-generation, higher-frequency bonding device targeting the battery and semiconductor markets.

Ruten, a Japanese-founded startup, has raised $2 million to develop an invasive BMI called Swallow Autopilot for people with dysphagia. The round was led by Tokyo-based Coral Capital via a SAFE instrument.

Japanese graphene startup 3DC has closed the second tranche of its Series A round, bringing total fundraising to $18 million. The company is commercializing Graphene MesoSponge (GMS), a three-dimensional graphene material that combines sponge-like flexibility with high electrical conductivity, targeting lithium-ion and next-generation battery applications.

Solafune, a Tokyo-based startup building a Planetary Intelligence OS across GEOINT, SIGINT, and OSINT, has raised over $32 million in Series A funding. The company already counts Japan's Ministry of Defense among its clients and is expanding into African markets.
