Bachis are the sticks used to play the traditional Taiko drum, and for Taiko no Tatsujin they are attached to the cabinet available for any players to use and MyBachis are personally owned and highly customized versions that some players choose to own.
As of now, the Official MyBachi pre-orders of either red or blue will be available at select
Namco arcade stores until February 14 2016
following the early March release. Purchasing the sticks by this method also gives you a bonus outfit to use in game. A limited stock will also be available at the four sessions of the Next-Generation World Hobby Fair ’16 Winter
event in Tokyo, Nagoya, Osaka and Fukuoka. Other further releases will be continually decided and announced as time goes.
