“Umi Kagan” is an Okinawan phrase meaning “the sea reflecting the sky like a mirror.” The design of this series is inspired by the ever-changing colors of the winter sea in Okinawa, where strong winds move the clouds swiftly, casting reflections of shifting light.

Created with the concept of embracing change and individuality, the Umi Kagan series combines the depth of black with the purity of white, symbolizing confidence and freedom. Its chic yet elegant appearance makes it ideal for both daily use and special gatherings.

This set includes a beautifully designed sake bottle (tokkuri) and two sake cups (guinomi), elegantly packaged in a gift box — perfect for gifting or personal enjoyment.
