Japan 100 is a quest board for your trip: 100 uniquely Japanese things to actually do, from slurping ramen properly to climbing Mt. Fuji. Pick a quest, do it for real, snap a photo, and it's sealed with a red hanko stamp. Every quest includes an etiquette tip so you get it right the first time. Commons, rares, and eight gold legendaries. Export your board as a share card. No account, no servers: photos stay on your phone. First 30 quests free; one purchase unlocks all 100, no subscription.










Hi Product Hunt! I'm Yuiko, and I built Japan 100 solo.
Guidebooks tell you what to see in Japan. They rarely tell you what to do. What people actually retell after a trip are actions: slurping ramen the way locals do, getting a deer in Nara to bow back, working up the nerve to duck into a six-seat bar under the train tracks. So I wrote down a hundred of those and built an app around the list.
How it works
Pick a quest from the board. Do it in real life. Snap a photo as proof. The photo becomes the card and a red hanko stamp slams down over it, the same seal that makes paperwork official in Japan. That moment is the whole app.
What's on the board
Everyone gets the same 100. Commons you can do before breakfast (unwrap an onigiri without tearing the nori, crack a raw egg over rice, stamp your notebook at a train station). Rares that take a booking or some nerve (a night at a ryokan, one shot of kyudo, a sand bath in Ibusuki). And eight gold legendaries: hanami, kabuki, a real matsuri, fugu, snow monkeys in the hot spring, sumo, a geisha performance, and Mt. Fuji at sunrise. Three of those are season-locked, so a perfect 100 in one trip is nearly impossible on purpose.
Every quest teaches the etiquette
Why the ¥5 coin is the lucky one for the offering box. Why you wash before the onsen and never photograph the bath. Why the appetizer you didn't order at the izakaya is the seat charge. I cut dozens of quest ideas that would have made tourists a nuisance to locals. Doing the thing properly is half the fun.
Your photos stay yours
No account, no sign-up, no servers. Photos and progress live only on your phone.
Pricing
The first 30 quests are free. One purchase ($19.99) unlocks all 100. No subscription, because a trip lasts two weeks and nobody wants a vacation tax.
iOS today, Android next. I'd love to know: if you've been to Japan, which quest would you add? And if you're going, how many do you think you'll seal?
