Roppongi for builders & founders
Meet investors, partners and the first believers in what you’re building. Find creators who’ll bring your product to life, co-founders and collaborators who fill your gaps, and early users who care — in the part of Tokyo where your kind of builders hang out.
Why Roppongi
Roppongi went from nightlife to skyline. Roppongi Hills, Tokyo Midtown and Azabudai Hills now house investors, global companies and art museums; Tokyo Tower watches over the accelerators at its feet. It’s where Tokyo meets the world.
Come here to pitch, to partner and to find the people who’ll take a bet on you.
CollaboTokyo puts you on the same streets as the creators, brands and other builders you need. Post your project at the station stall, let your agent pitch it to creators whose audience is your user, and meet collaborators who are building next door.
