Stretching & Bodywork Salon "Karada Stretch" to Start Selling Original Protein "BALANCE PROTEIN" from May 8th

Stretching & Bodywork Salon "Karada Stretch" BALANCE PROTEIN

Factory Japan Group Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and President: Hideki Haruna; hereinafter "Factory Japan"), which operates stretching and bodywork salons such as "KA・RA・DA Stretch" (hereinafter "Karada Stretch") both domestically and internationally, will begin selling its original protein from May 8, 2026 (Friday). The aim is to help maintain the body conditioned at "Karada Stretch" for as long as possible, and to care for daily concerns as they arise to maintain a healthy body.

Unlike general proteins primarily intended for muscle building, this product is designed with a focus on "rest," "condition care," and "ease of continuation."

## Features of the Original Protein Product "BALANCE PROTEIN"

1. Protein for "Conditioning" rather than "Training"

Karada Stretch values "conditioning" through its treatments. Following the same philosophy, this protein is designed to maintain and improve physical condition, not for muscle mass gain. Soy protein (soybean) was chosen as the ingredient because it is plant-based, contains isoflavones, and is judged to be easy for a wide range of customers to continue using. It is designed to be easily incorporated into daily life.

2. Pursuit of Drinkability with a Soy Protein Base

Based on plant-based protein, it achieves a taste and texture that are easy to continue. In taste tests, it received high evaluations for "drinkability" and "mixability."

3. Ingredient Blend to Support Daily Condition Maintenance

It contains a balanced blend of ingredients for internal maintenance, including dietary fiber and lactic acid bacteria for internal cleansing support, zinc for daily health and beauty support, and carnitine for active daily life and nutritional support during exercise.

Karada Stretch will continue to strengthen its self-care proposals in addition to its treatments, aiming to provide more diverse value. We will contribute to improving customers' health and quality of life (QOL) by achieving "body care that includes daily life, not just time spent at the salon."

Please look forward to future developments.
