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.
