Challenges

Over the years, there have been a few foolish challenges at Tsurugi, first Wasabi Challenges, then the rather dangerous Soy Sauce Challenge. The format has been fluid, either a 1 on 1 battle where the winner progresses to face the next challenger and all are welcome to re-challenge champs, or battle royale style, where there can be only one at the end. There have been two challenges in the past (emphasis on in the past):

Wasabi Challenge

eating extra-wasabi-laiden wasabi rolls until someone catches fire or drinks all the saki at the table and passes out

Soy Sauce Challenge

taking soy sauce shots until someone vomits or has a heart attack, which ever comes first

All such challenges are BANNED - wasabi is painful and can cause some nasty indigestion, and while soy sauce is said to be better for you than red wine, too much is no good.
