EnjoyLearning Old Japan Puzzle

EnjoyLearning Old Japan Puzzle is a compact educational Chrome extension that teaches the old Japan map through a jigsaw puzzle format. Inspired by a puzzle-style map game produced by Digital Gene, it remains simple yet fun for both geography enthusiasts and learners prepping for exams.

It features three play modes (time trial, versus, and completion) with a panel-collection system and an assist function to locate places. Note: Hokkaido and Okinawa are not included; Mutsu and Dewa are the pre-Meiji states.
