Nintendo has revealed that the upcoming Switch title Super Smash Bros. will be playable at a series of events in Japan during June and July.
The demo will kick off its Japanese tour at RAGE 2018 Summer, which takes place on June 17th at Makuhari Messe, Chiba. A week later it will be at Jisedai World Hobby Fair ‘18 Summer in the same location, and then on July 16th it will be at Jump Victory Carnival 2018 Tokyo - again at Makuhari Messe. The final date is July 22nd, when it will be playable at Jump Victory Carnival 2018 at the Intex, Osaka.
Given the timing of these events, it's fair to assume we'll be seeing a lot of this game at E3, which takes place on June 12th.
