Aomori field report: Custom undershirts, from baseball to everyday life
Inspired by high school baseball in Aomori, we introduce GINNIE undershirts and the appeal of a personal design for sport and everyday life.
We are heading out on sales visits in Aomori City, where the excitement is still fresh from Hachinohe Gakuin Kosei’s hard-fought prefectural championship victory and the outstanding play of all the high school baseball players!
The emotion and passion of those moments have set our own hearts ablaze!
This autumn, bring out your best performance with a one-of-a-kind shirt.
In the final of the 79th Autumn Tohoku District High School Baseball Aomori Prefectural Tournament on September 20, Hachinohe Gakuin Kosei won a fierce contest against Aomori Yamada 5–3, claiming their second consecutive title and their 19th overall! The players’ sweat, hard work, and determination on every pitch are truly moving.

To match that passion, we offer custom undershirts for baseball players, coaches, managers, and everyone who loves sport.
Our undershirts are more than just baseball wear! Loved by professional baseball players, their exceptional comfort and functionality have also won fans across a wide range of activities and everyday settings.
- Athletes in horse riding, football, swimming, and other sports
- YouTubers looking to express their personality on camera
- As sleepwear for relaxing in exceptional comfort at night
