• Qubitcore

  Participated · Seed · Apr 2026

  Founded in July 2024, Qubitcore builds on OIST research to integrate ion-trap quantum processors with micro optical resonators to enable high‑efficiency photon–qubit interfaces and multi-module optical connections. The company aims to realize fault-tolerant quantum computers via a distributed quantum computing architecture and holds an exclusive license with OIST signed in July 2025. Its roadmap targets a cloud-accessible quantum computer prototype operating at OIST in 2026, an Early‑FTQC with error‑correction capabilities by 2028, and a second‑generation multi‑QPU optically connected system by 2029. Qubitcore has strengthened its financial position through a ¥1.53 billion seed round led by SBI Investment, following a pre-seed in January 2025, and plans to deploy funds into R&D, partner/validation activities, and hiring. The company operates its headquarters in Yokohama with R&D facilities and labs based at OIST in Okinawa.

• Metro Weather

  Participated · Series B · Aug 2025

  MetroWeather has developed a compact Doppler lidar that uses infrared lasers to visualize wind direction and speed over a wide area in real time, with observation data shown via a proprietary UI. The company’s strengths include signal analysis algorithms from years of atmospheric remote sensing research and a domestically optimized lidar design that integrates hardware and software. Its design reduces device size compared with conventional models while accurately measuring wind conditions up to approximately 15 km. Current customers and use cases include offshore wind power generation, airport management, and marine sports events. The firm recently raised capital (see deal) and plans to use proceeds to establish a mass production system, pursue dual-use deployment for defense and civilian applications, and fund R&D of next-generation models with object detection. MetroWeather aims to supply mass production models starting in 2025 and to contribute to safe infrastructure globally through expanded commercialization. Metroweather designs and manufactures Doppler‑lidar devices that use infrared lasers and signal processing to measure wind direction and speed in three dimensions in real time. Its systems can detect wind over a roughly 10–15 km radius and perform well in low atmospheric layers where radar is limited. The company highlights applications for safe drone and eVTOL operations, including expanding use cases for suspicious‑drone detection and other security applications. Metroweather’s technology was adopted by NASA in 2021 and has been deployed to a NASA drone test field in the current fiscal year. The firm is pursuing international expansion, notably accelerating U.S. business development. Financially, the company has increased its Series A cumulative funding to ¥1.2 billion following the latest extension.

• Amogy

  Participated · Equity · Jan 2025

  Amogy builds modular ammonia-to-power systems that crack ammonia into hydrogen and feed the resulting hydrogen into a fuel cell or engine, enabling carbon-free electricity generation. The company targets hard-to-decarbonise sectors, with current focus on maritime propulsion, distributed generation, and floating power infrastructure. Its plug-and-play modules are designed to integrate into vessels or barges, providing fast-deployable, high-density power. Amogy is now exploring the use of its technology on Powerships and floating data-centre platforms through a new partnership with Kinetics, a subsidiary of Karpowership. By pairing on-board ammonia storage with at-sea operations, the approach could circumvent on-shore permitting delays while leveraging seawater cooling for improved energy efficiency. The collaboration aims to serve multi-hundred-megawatt AI and digital-infrastructure loads, contingent on developing adequate ammonia bunkering and grid connections. No revenue or user metrics were disclosed in the article, but management positions the solution as a key enabler for rapid, large-scale decarbonisation in high-demand markets.

• Turing

  Participated · Series A · Apr 2024

  Turing develops fully autonomous driving technology originating in Japan. The company is scaling its computing infrastructure and commercial operations as it moves toward real-world deployment. In its Series A and extension rounds the company has raised a cumulative ¥27.89 billion (about $174 million), including ¥12.62 billion (about $79 million) in the recent extension. Turing plans to use the new funding to expand compute capacity, strengthen its business organization for deployment, and hire additional staff. The company’s stated goal is to accelerate realization of Japan-developed fully autonomous driving systems.
