Bandai Namco has announced fishing game Bakutsuri Bar Hunter for Switch in the latest issue of Monthly CoroCoro Comic.
In March 2018, Bandai Namco released Bakutsuri Bar Hunter for 3DS in Japan. Based on the cross-media franchise of the same name, the 3DS game was a free download that utilized the physical “Bakutsuri Bar Rod” fishing reel peripheral. Read more about the 3DS version here.
At this time, it is unknown whether the Switch version is a port of the 3DS version or a new game entirely, or whether it utilizes a peripheral.
