LUNDATTE Inc. (Headquarters: Chuo-ku, Tokyo; CEO: Chiaki Kimura) will be showcasing and selling its signature product, Choii Boxers, a seamless high-waisted boxer brief designed for men, at the “Yokohama Women Entrepreneurs COLLECTION 2025” held at the Yokohama City Hall Atrium on Thursday, September 4, 2025. A new color will also make its debut at the event.

This marks the first in-person sales opportunity for general customers to see and purchase the product, which has primarily been available through our official online store.

About Choii Boxers

Choii Boxers were born out of the desire to create innerwear that is both comforting and stylish for men prone to digestive discomfort. To achieve a structure that could not be reproduced with conventional manufacturing methods, LUNDATTE approached over 100 sewing factories and spent three years in development. It has now been approximately one year since the product successfully launched.

Today, 1 in 7 adults is said to suffer from gut-related issues such as IBS (Irritable Bowel Syndrome) (※1). While there are many ways to cope with cold and stress, there have been few underwear options that serve as self-care simply by wearing them.

LUNDATTE challenges the conventional idea of innerwear. We believe that taking care of your inner body directly impacts your overall condition, and we redefine underwear as something that supports both physical movement and emotional comfort.

This exhibition has been officially selected as part of the Yokohama City “Shining Women Entrepreneurs Promotion Project”, and is conducted with support and collaboration from the local government.

Looking ahead, LUNDATTE plans to further promote Choii Boxers as a new category of fashion item that brings beauty to the unseen, with future applications in sports, fitness, and co-creation projects.
