About CO-DEJIMA
Dejima was once the only place in Japan open to the world.The people who thrived there were innovators, full of the spirit of challenge.
CO-DEJIMA brings that “Dejima spirit” back to life today,as a startup hub that helps ideas become businesses.We are not as big as Dejima once was.
But when it comes to the size of our dreams, we won’t be outdone. We aren’t afraid to fail.Let’s work hard, laugh, and take on challenges together.
Let’s change the world, starting here.
