Japanese Rail Sim 3D: 5 Types of Trains (known in Japan as Tetsudou Nippon! Rosen Tabi: Oumi Tetsudou-hen, which loosely translates to "Railway Japan! Every Route: Ohmi Railway Edition") is a train driving simulation game developed and published by Sonic Powered for the Nintendo 3DS in Japan on May 21, 2015 (as a retail release) and in North America on November 22, 2018 (as a downloadable title).
The fourth title in the Japanese Rail Sim 3D series (after Journey to Kyoto), 5 Types of Trains follows the Ohmi Railway's entire Main Line in the Japanese Shiga Prefecture (from Maibara in Maibara to Kibukawa in Kōka). As the overseas title shows, the game has five types of trains to choose from (each with their own cabin appearance and sounds), some of which are unlockable.
