SUGOCA (スゴカ Sugoka?) is a Japanese rechargeable contactless smart card ticketing system for public transport in Fukuoka Prefecture and environs. The Kyūshū Railway Company (JR Kyūshū) introduced the system on 1 March 2009. The name is an acronym of "Smart Urban GOing CArd", while sugoka (凄か?) in the local Kyūshū dialect means "great". Like other electronic fare collection systems in Japan, the card uses RFID technology developed by Sony Corporation, known as FeliCa. American graphic artist Rodney Greenblat designed its official mascot, a frog with a clock.
On March 13, 2010, SUGOCA has been interoperated with two similar cards in Fukuoka—namely nimoca by Nishi-Nippon Railroad (Nishitetsu) and Hayakaken from Fukuoka City Transportation Bureau—plus Suica, a card used in Greater Tokyo Area by East Japan Railway Company (JR East). Additionally, since March 5, 2011, in a reciprocal agreement with Central Japan Railway Company (JR Central) and West Japan Railway Company (JR West), SUGOCA is also usable in Osaka-Kobe-Kyoto, Okayama-Hiroshima and Nagoya metropolitan areas. Similarly, the TOICA card of JR Central and the ICOCA card of JR West can also be used on JR Kyushu rail services.
