Shoko

What Shoko does

Shoko Co., Ltd. (昭光通商株式会社) is a Tokyo-headquartered Japanese materials trading company (sōgō shōsha) founded in 1947 as Hikari Kogyo Co., Ltd. with support from Resonac Corporation (formerly Showa Denko) and Ajinomoto. The company operates three divisions — Chemicals, Plastics (Synthetic Resins), and Metal & Ceramics — distributing organic and inorganic chemicals, polyethylene and polypropylene resins (over 200,000 tons annually), aluminum products, ceramics, carbon materials, and refractory goods to manufacturers across automotive, electronics, pharmaceutical, food, construction, and agriculture sectors. It also holds proprietary manufactured products through subsidiaries including SDAT (aluminum processed products, thermocoil heat exchangers, LNG vaporizers, IoT Thermo Coil monitoring system), Shoko Science (analytical instruments and stable isotopes), and Shoko Highpolymer (functional resins).

Revenue is generated primarily through transactional trading margins on chemical, resin, metal and ceramic distribution, supplemented by hardware sales from SDAT's manufactured products (aluminum processed goods, thermocoils, evaporators) and Shoko Science's analytical instruments. The company was taken private in November 2021 following a TOB by SKT Holdings K.K., delisting from the Tokyo Stock Exchange First Section after decades of operation as a publicly listed entity (listed since 1962). Operations span 5 domestic offices and overseas subsidiaries in South Korea, Taiwan, Thailand, and a Shanghai representative office, with 390 consolidated employees as of December 31, 2025 and paid-in capital of ¥5.035 billion.

Distribution is direct B2B through dedicated sales teams at Tokyo headquarters and four regional offices (Osaka, Nagoya, Fukuoka, Oita), supplemented by overseas subsidiaries. The customer base exceeds 500 partner companies across multiple verticals. Recent strategic emphasis is on sustainability-aligned products — Nature Master biodegradable mulch film (3,000+ cumulative units shipped), Re-Pole recycled aluminum poles (~90% CO2 reduction), LoopAL low-carbon aluminum plate, and IoT Thermo Coil decarbonization visualization — alongside targeted growth in the Metal & Ceramics Division, which targets 1.5x revenue growth to ¥450 billion by 2030 ahead of an intended 2026 re-listing.
