Founder Program

Growing the Forest of Innovation

At Sayama Ventures, we see startups not as mere businesses, but as living ecosystems. Each founder arrives as a seed carrying the potential for change, and every revolutionary idea is a fragile sprout. We understand that challenges are not roadblocks, but essential seasons to grow through, deepening roots and strengthening resolve.

Our singular vision is to be Japan’s most inspiring venture builder, the modern forest of innovation. This is where creativity, courage, and collaboration take deep, unwavering root.

Our inspiration is drawn from the mystical Sayama woods, the enchanted setting that sparked Miyazaki’s Totoro. Like those woods, we believe in invisible forces: the unseen, powerful connections between people, purpose, and possibility.

- Magic begins when we align these forces:

- When founders feel completely supported.

- When raw imagination is given clear, helpful structure.

- When a powerful vision is matched with genuine wisdom.

At Sayama, we don't just invest; we cultivate. We are growing a resilient, magnificent forest where the future of innovation can thrive.
