Family Business

Kamui
Whisky K.K.

We hold shares in Kamui Whisky K.K. — a craft whisky distillery on Rishiri Island, Japan's northernmost distillery, deep in Hokkaido's remote wilderness. A unique, family-founded business building something genuinely rare.

🚀 Venture Investing

Angel Investing
in Japan

Small ticket sizes, early stage. We look for genuine problem/founder fit, people who are clearly the right person to be building this exact thing.

We don't invest in decks. We back founders.

🏡 Short-Term Hosting

A Few Unique Properties

We manage a small number of individual short-term rental properties — each one chosen for character rather than scale. Early days, growing slowly and intentionally.

💡 Founder Consulting

Early-Stage
Consulting

We work directly with founders at the finding-PMF and early-PMF stages — as a fractional Chief Product Officer and go-to-market strategist. Hands-on, not advisory-board distant. If you're trying to figure out what's working, why it's working, and how to do more of it — that's where we operate.
