Sanyo Shokai's women's apparel brand "TRANS WORK," one of its core businesses, has begun selling three types of blouses and one type of pants (four styles in total) that adopt "Dantotsu Oil®," a durable stain-resistant processing developed by Komatsu Matere Co., Ltd. (hereinafter referred to as Komatsu Matere), at department stores and directly managed stores nationwide, as well as on Sanyo Shokai's official online store, "SANYO ONLINE STORE."
In recent years, with the prolonged summer and rising temperatures due to climate change, Sanyo Shokai has, since 2024, approached the seasons not as four, but as "five seasons," and has been selling products according to a calendar that extends the demand period for summer clothing from the conventional three months to five months. In this environment, in addition to comfort and functionality, there is a growing need for designs that look good on their own and can be worn in any situation. Based on these changes, our company is promoting product development under the theme of "smart clothes adapting to climate change" for the Spring/Summer 2026 season. This product is part of that effort, developed through the company-wide "Product Development Committee" (*1).
This product combines consideration for stains that easily attach in daily life with added features such as contact cooling and UV cut functions for comfortable wear, and a design that can be utilized both on and off-duty. Specifically, we are proposing blouses and pants available in three colors: white, which allows users to easily experience the stain-resistant effect, black, which is easy to coordinate, and a accent color, royal blue, enabling wear without worry even in hot weather.

■Background of Product Development
~Sanyo Shokai's Product Strategy to Respond to Climate Change~
In recent years, Japan's climate has undergone significant changes, with record-breaking heat continuing for three consecutive years until 2025, and a marked trend of prolonged summers and rising average temperatures.
The long-term forecast announced by the Japan Meteorological Agency on February 24, 2026, also indicates that the average temperature for this summer (June-August) is expected to be higher than usual, making severe heat a new normal.
In this environment, consumer purchasing behavior shows an increasing trend towards demand-driven purchases, where clothes suitable for the actual temperature are bought at the necessary time, and clothing is increasingly required to have both functionality and versatility.
To respond to this change, Sanyo Shokai has divided summer into two parts, "early/mid-summer" and "extreme heat," viewing the seasons as "five seasons" instead of four, and is strengthening product development with a long, hot summer in mind. For the Spring/Summer 2026 season, under the theme of "smart clothes adapting to climate change," the company is focusing on strengthening light and medium-weight clothing, expanding its range of tops that look good on their own and bottoms with functional features. By combining trend elements with functionality, the company aims to achieve both fashionability and practicality.
~Product Development to Address the Summer Concerns of Working Women~
Amidst these trends, "TRANS WORK" has focused on reducing stress for working women when wearing clothes. Particularly in business settings, discomfort due to sweat and the adherence of stains such as sebum are obvious concerns. White shirts, blouses, and white pants, while highly demanded in spring and summer for their clean and light appearance, tend to be avoided due to concerns about stains, creating a need for added functional value.
"TRANS WORK" has promoted the development of highly functional and practical tops and bottoms through the company-wide "Product Development Committee" (*2). In selecting materials, the company rigorously evaluated materials that met three criteria: "stain-resistant and washable," "comfort," and "a neat appearance." The durable stain-resistant processing "Dantotsu Oil®" from Komatsu Matere Co., Ltd. was noted. Based on stretch materials with functions such as contact cooling and UV cut, which are comfortable to wear in summer, "Dantotsu Oil®" processing was applied, and fused with the brand's expertise in elegant and sophisticated designs. The goal was to develop products that can be worn without worry even in hot weather.
