Ganbare Goemon: Dosukoi! Harite Ichiban (がんばれゴエモン ドスコイ！張り手一番) is a Fighting Sumo mobile game which was developed and published by Konami on December 16, 2002 in Japan, for mobile phones. It is the first game and it is part of the Ganbare Goemon: Tsūkai Game Apli series, but was based of the video game Ganbare Goemon 2: Kiteretsu Shōgun Magginesu.
The Goemon's Companion, Yae, has joined with "Hearts", go said to be hidden "Zubari" calling The Caves of the Heart", but the cave was submerged. So Yae's new technique "Martial arts change technique" comes in!
