When the interoperation between ICOCA and Suica started, TV commercials and other advertisements were publicized for several months, in which with the appearance of a huge Ico the Platypus in Tokyo, NAKAMA shouted 'In Tokyo...!' and in continuation Ico the Platypus shouted 'ICOCA...! (Let's go...!).'
ICOCAとSuicaの相互利用開始時に、巨大化したイコちゃんが東京都内に出現し、仲間が「東京で～」イコちゃんが「ICOCA～」と叫ぶテレビCMや広告が数か月間に亘って宣伝された。
