 KEN Singles Hero Last Chance Qualifier
|
SWT: Japan Ultimate Online Qualifier was the sixth Super Smash Bros. Ultimate qualifier for Phase One of the Smash World Tour 2021. It is region locked to Japan. The top six players of the main bracket and the top two players from the Last Chance Qualifier were invited to the Phase Two tournament SWT: East Asia Ultimate Regional Finals. All players from Southeast Asia were unable to attend the Regional Finals due to COVID-19 travel restrictions, so they were replaced by eight competitors from Japan who attended this tournament.
