How to play & examples
This guide is available in Japanese and English.
Pick a tool to spark a conversation with friends or a little adventure outside. Neither tool requires an account.
First Come, Secret Shared
Set a participant target, then share text or one photo with the first participants for 24 hours after the target is reached.
- Separate your teaser from your secret. The teaser is visible to people with the link. The secret text and photo stay hidden until the target is reached. Include text, a photo, or both.
- Choose a target and create a link. The range is 1–100,000. For a first try, choose a small group you can actually invite.
- Share the link. Browsers secure a place when their join request completes. The creator also uses a place if they open the participation page and join.
- Enjoy the reveal together. Only browsers with a place can read the secret after the target is reached. New participants cannot join after the reveal.
If the target is not reached, viewing ends seven days after creation. If it is reached, viewing ends 24 hours after the reveal. Expired content is scheduled for deletion. Creators can withdraw a post earlier from “My secrets” in the same browser.
Clearing cookies can remove participation and management access. Screenshots, copies and reposts by viewers cannot be prevented. Do not post personal information or photos of others without permission.
Create a secret ↗Outing Challenge Maker
This tool does not decide your destination or budget. It combines an activity to try outside, a matching photo challenge, and a way to report the experience on social media.
- Draw your challenges. Redraw any item you cannot do. Changing the activity also changes the photo challenge to match.
- Try it at your own pace. Choose where to go and what to spend. Respect photography rules and ask permission where needed.
- Save a challenge image. Choose feed size (1080×1350) or story size (1080×1920), then download a PNG.
- Share your challenge or experience. Use the device share menu, X, Threads, Facebook, LINE, or copy the link. Create and publish your actual photos and final post in your own social app.
Shared links contain challenge indices and a language. The same link opens the same challenges, even after a language change. There is no photo upload or location submission feature.
If your device cannot share image files directly, save the PNG and attach it in your social app. For Instagram, use saved images and copied text. Nothing is posted automatically.
