C108 maps ready. Your all-in-one prep tool for Summer Comiket — circle management, budget calc, change calc & AI scanner. Works offline at the venue. No ads.

Torehan is your all-in-one companion for Japanese doujin events — Comic Market (Comiket), Comitia, Design Festa, 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 Event Day Unlock; 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.
