Sumo Kaboom

Leslie and Laurie Collins, Texan sisters and diehard sumo fans, talk about all things sumo.

About the show

Sumo Kaboom!

A weekly podcast dedicated to our favorite sport - sumo wrestling. We chat about tournaments, current events, history and our favorite wrestlers.

Both Collins sisters are performers, improvisers, and creators and have absolutely no sumo training. But, they are huge sumo fans.

Having lived in Japan, Leslie loves the history and traditions of sumo. She also has a deep love for sumo karaoke singers. Laurie is fascinated by sumo wrestler fandom, the sumo training regimen and physicality of the sport.

Together, they serve up exciting sumo treats for sumo-curious fans. These kooky sisters share an enthusiasm for sumo and like all sisters, they work amazingly well together. All of the time. There are never any issues. Ever.

We also occasionally send out sumo related content. It is NOT hard-hitting sumo journalism and is usually very silly. If you want to receive our writing about all things sumo or receive notification when Sumo BINGO cards are available, join our Substack below. We won't ever share your info.
