This mug was designed by Sven Kirsten for Kahuna Tiki and Kahuna Tiki TU. It is a Lono tiki head that incorporates the Samurai "Mempo" facial mask imagery and features a Samurai sword on the reverse stabbing a fish (inspired by vintage OMC Samurai Grog Mugs and also alluding to this being a sushi establishment).

This darker Indigo Blue Edition was initially released in part at the September 2022 Kahuna Tiki Tu Marketplace. Still available as of November 2022 on location at the restaurant.
