Jagi's iconic helmet has been transformed into a stainless steel sake cup using precision casting technology.
It comes with a dedicated wooden base, making it a substantial and impressive item that can be enjoyed as a display piece.

Castem Co., Ltd. will release "Jagi's Sake Cup," a metal sake cup modeled after the iconic helmet of "Jagi" from "Fist of the North Star."
This product is a sake cup that reproduces the distinctive shape of Jagi's helmet in stainless steel using Castem's unique technology as a precision casting manufacturer. It will be available for purchase from 10:00 AM on Friday, May 8, 2026, at the domestic e-commerce site "Castem Rakuten Market," the cross-border e-commerce site "eBay," the physical store "meta mate Eslite Spectrum Nihonbashi," and other retailers for 9,900 yen (tax included).
Reproduced using precision casting technology

These sake cups are made of stainless steel using the precision casting technology (lost-wax casting method) that Castem, a company with 55 years of experience, specializes in.
Precision casting, unlike conventional casting, is a casting method well-suited for expressing delicate and flexible shapes. The substantial weight inherent in metal casting is also a major appeal.
Meticulous design




While retaining the distinctive design of Jagi's helmet, the design has been stylized to be easy to use as a drinking vessel, with consideration given to preventing spills and making it easy to drink from.
Additionally, it comes with a dedicated wooden base, allowing for stable display even when not in use.
This playful sake cup lets you enjoy your drink while feeling like you're Jagi.
"Say my name!!"
...you might be tempted to shout that out, but please enjoy alcohol in moderation.
