3 things Torehan! does for you

Can't read the circle names? You don't have to.

1Circle and item names, translated into your language

Circle names, creator names and the items on each circle's list are almost always written in Japanese. Tap Translate and they're shown in your app language — so you know what you're lining up for before you join the queue. Prices stay in yen, exactly as listed.

Example (for illustration)

新刊セット ¥1,500New release set ¥1,500
アクリルスタンド ¥1,200Acrylic stand ¥1,200
既刊 ¥500Back issue ¥500

Translation is optional and only runs when you tap Translate. It uses AI provided by Anthropic: circle names, creator names and item names are sent to it to be translated. The first 10 circles are free, then ¥100 for 50 more circles. Translations are saved on your device, so viewing a circle again doesn't use your count, and the Japanese original is kept.

Menus, buttons, guides — all in your language

2The whole app speaks your language

No more wandering the halls looking for a circle

3Venue maps and budget, in one place

See where each circle is on hall-by-hall venue maps; pinch to zoom and mark circles right on the map. Your list adds up the total you'll need (in yen), and you can check off what you've bought so nothing gets missed.
