Mejiron Nimoca

Mejiron Nimoca (めじろんnimoca) was a rechargeable contactless smart card ticketing system for public transport in Oita Prefecture, Japan. Oita Bus, Oita Kōtsū, and Kamenoi Bus introduced the system on December 26, 2010. Like other electronic fare collection systems in Japan, the card uses FeliCa, RFID technology developed by Sony. The design of the card features nimoca's ferret mascot Nimoca-chan alongside Mejiron (めじろん), the mascot character of Oita Prefecture.

Tte card (along with the normal nimoca variant) was initially usable on local bus lines operated by Oita Bus and Oita Kōtsū, with expanded support to more operators beginning March 20, 2011. As Mejiron Nimoca and nimoca had integrated services, SUGOCA, Hayakaken, Suica, and other Japanese IC cards were also usable in the area.

Sales of Mejiron Nimoca cards ended in 2014, with all existing operators transitioning to the standard nimoca design.
