A Playasia listing confirms Super Dragon Ball Heroes: World Mission will also be getting an Asian physical version with English support.
How about the West?
Previously, Super Dragon Ball Heroes: World Mission was announced heading to Japan on 4th April 2019. At the moment, there have been no word yet for a western localization.
Super Dragon Ball Heroes: World Mission was given an official rating by the video games classification board in Australia. But if that signals a Western release is unsure at the time.
With the Asian release revealed, more will now have access to the game. As with the other Asian releases, this version will of course work on all Nintendo Switch systems worldwide thanks to it being region free BUT some online features might need a Nintendo Account with a region set in Asia to work … or might even work less good as the infrastructure is in that region and you are not.
