Konaka Co., Ltd. Launches "4S AIR" Series, a Lightweight Solution for Extreme Heat, on April 16, 2026

Konaka Co., Ltd., headquartered in Yokohama, Kanagawa Prefecture, and led by CEO Kensuke Konaka, will launch the "4S AIR" series under its "SUIT SELECT" brand, which operates under the concept of "real suits." The launch date is April 16, 2026 (Thursday), with a gradual expansion of items. The "4S AIR" series builds upon the functionality of the successful "4S" series, specifically addressing the discomfort of hot and humid weather from early summer through the rainy season and peak summer. Recent meteorological data indicates that Japan's average temperature for summer 2025 (June-August) reached a record high since statistics began in 1898. The deviation from the average was +2.36℃, significantly surpassing the 2023 and 2024 records (+1.76℃). Additionally, the rainy season began in May and ended in June in most regions (excluding Tohoku), marking a historically early start and end, leading business professionals to prepare for summer earlier each year. SUIT SELECT aims to address this trend of early extreme heat by introducing "4S AIR" from April. The current business wear market emphasizes "comfort" and "functionality," with high demand for "stretch materials," "cool-touch materials," and "easy-care materials." There is also growing interest in "setup styles" and "pattern orders," reflecting a desire for personalized comfort. The "4S AIR" series is designed to provide coolness with every breeze, achieved through extremely lightweight materials and components. Its four core concepts are: 1. SHEER BREEZE: Coolness from thin, light, breezy materials. 2. SUPER NON IRON: Easy care, machine washable, no ironing required. 3. STRETCH: Easy movement with 2-way stretch (vertical and horizontal). 4. SOFT TOUCH: Supple texture with good drape. The "4S AIR" product lineup includes: 1. "4S AIR SUIT": From 31,900 yen (tax included). Achieves over 15% weight reduction compared to conventional summer suits. Features an unconscious specification suitable for both tied-up and business casual styles. 2. "4S AIR SET UP": Jacket 26,400 yen (tax included), Pants 10,890 yen (tax included). Allows for flexible mix-and-match combinations. Includes both tapered pants and trendy wide-leg pants models. 3. "4S AIR ORDER": From 53,900 yen (tax included). Available in 4 colors of cool mesh-like fabric. Offers custom tailoring (pattern order) to fit body types and preferences. 4. "4S AIR SHIRT": 5,390 yen (tax included).

"SUIT SELECT" is a brand comprehensively supervised by Kashiwa Sato, themed "Choose, Wear, Enjoy."
