Revolutionary 4S AIR Launches to Combat Rising Summer Temperatures This April

Introducing the 4S AIR Series

On April 16, 2026, Konaka Co., Ltd. will introduce the much-anticipated 4S AIR series from its SUIT SELECT line, aimed specifically at countering the extreme heat that has been affecting summer seasons in recent years. The company, led by CEO Kensuke Ko-naka, is committed to creating business wear that combines functionality with comfort, and the 4S AIR series is no exception.

Rising Temperatures and Shifting Consumer Needs

According to the Japan Meteorological Agency, the summer of 2025 saw the highest recorded average temperatures since tracking began in 1898, surpassing the previous records by a significant margin. The early arrival of the rainy season in many regions, excluding Tohoku, has prompted business professionals to prepare for summer sooner than ever before. To address this trend, SUIT SELECT aims to cater to consumers' needs by launching the 4S AIR series early in the season.

Market Trends: The Demand for Comfort and Functionality

In today’s business apparel market, comfort and functionality are the primary focus. Fabrics that offer stretch, cooling properties, and easy care are becoming increasingly popular, with many consumers seeking garments that provide a customized fit. The growing interest in set-ups and made-to-order options highlights the demand for personalized comfort and style.
