About this app

Torehan is your all-in-one companion for Japanese doujin events — Comic Market (Comiket), Gakuen Star Festival, IDOL STAR FESTIVAL, Holokle, and more.

Perfect for first-timers, too — if it's your first Comiket or doujin event, Torehan helps you navigate the venue, plan an efficient route, and prepare your budget so you won't feel lost on the day.

Map display and circle management run on-device, so the core app stays smooth even when venue networks are congested.

■ Key Features

◆ Circle Management
Save the circles you want to visit, attach their menu (oshinagaki) images, and zoom in to check the details before you go.

◆ AI Menu Scanner
Point your camera at a circle's booth menu to automatically extract the circle name, items, and booth location. Two modes:
· Cloud OCR — high accuracy, credit-based (credits included with the Prep Pack; top-up packs available)
· On-device OCR — free, unlimited, fully offline, no data sent externally

◆ Hall Maps
Pinch-to-zoom hall maps, pre-loaded with no import needed. Mini-map highlights your current hall in red.

◆ Budget Calculator
Total up your wishlist before the event to plan your budget. Skip the 30–60 min ATM queue on the day.

◆ Change Calculator
Check off your picks and see your change amount live on the map screen.

◆ Share & Split Lists (optional)
Share your circle list with friends via an invite code, and split up who visits which circle.

◆ Community Circle Search (optional)
Search circles shared by other users and import them into your own list.

◆ Registrant Count Guide (optional)
See an estimate of how many users have saved each circle — a handy hint for predicting crowds on the day.

◆ Search
Search by circle name or X (Twitter) oshinagaki URL.

◆ Packing Checklist & Event Tips
Review your gear and get venue strategy hints — all in one place.

■ Highlights
· Core features (map display, circle management) run on-device — smooth even when venue Wi-Fi and cellular are congested
· Your data stays on your device by default. Data is sent externally only when you use an optional feature: Cloud OCR (image sent for AI analysis), or Share / Split / Community Search / Registrant Count (circle info, oshinagaki images, and a device identifier)
· No banner or video ads, no behavioral tracking
· 8 color themes
· 6 languages: 日本語 / English / 简体中文 / 繁體中文 / 한국어 / Français

■ Supported Events
· Comic Market (C107 / C108)
· Gakuen Star Festival 03
· IDOL STAR FESTIVAL 16
· Holokle 12th
Hall maps are built in for all of these events, and need no internet to view. More maps and events added regularly.

■ Who It's For
· First-time and beginner Comiket / doujin event-goers
· Anyone who wants to tour circles efficiently
· Groups splitting up a large event together

■ Free / In-App Purchases
The free plan allows up to 5 circles per event day. The Prep Pack removes that limit for the purchased event and day only.
· Prep Pack — unlimited circles for the purchased event/day + cloud OCR credits (consumable)
· Cloud OCR top-up — add more credits as needed (consumable)
· Strategy Pack — unlocks the registrant count display for the purchased event/day (consumable)
· Upgrade to Strategy Pack — the price difference, offered only if you already own the Prep Pack for the same event/day (consumable)
· Circle translation top-up — translate 50 more circles (consumable)

* Cloud OCR sends images externally for AI analysis. The Share, Split, Community Search, and Registrant Count features send circle info, oshinagaki images, and a device identifier to our server. On-device OCR (free) and core features have zero external transmission.
