Watanabe

What Watanabe does

Racing Service Watanabe (レーシングサービスワタナベ, RS Watanabe) is a Japanese privately held manufacturer of aluminum and magnesium alloy aftermarket wheels, founded in 1967 by Toshiyuki Watanabe as a racing car constructor and incorporated as a stock company in 1975. The company designs, casts/forges, and sells wheels primarily for motorsport, automotive customization, and classic car restoration applications. Its signature product, the "Eight Spoke" (エイトスポーク) 8-spoke wheel launched in 1968, is so closely identified with the brand that "8 spokes = RS Watanabe" is a recognized market identity in the Japanese aftermarket wheel industry. The company operates a vertically integrated manufacturing footprint, with headquarters and direct sales in Yokohama (Kanagawa) and a dedicated casting factory in Tomobe (Ibaraki) built in 1984.

The product portfolio spans both die-cast (金型) and sand-cast (砂型) aluminum wheels, forged (鍛造) aluminum wheels, and magnesium variants, offered in 1-piece and 2-piece constructions and sizes from 10 to 19 inches. Core lines include the Eight Spoke family (F8, F8F, R, A-disk, B-disk), the lightweight Forging R series (4.7kg aluminum, with Forging R MG magnesium forged at 4.5kg announced for winter 2025), heritage revival models (4S, GOTTI MG), the RS8R 1-piece eight-spoke, and nostalgic recreations such as HAKO-R (Hakosuka steel wheel reproduction) and PIERCE (commercial-van application). All products carry JWL/JWL-T certification, and the RM8 magnesium wheel achieved Japan's first VIA certification in February 1996.

Revenue is generated through made-to-order wheel sales distributed via a hybrid B2B/B2C model: authorized distributor Falcon Distributor (with its own e-commerce platform falcon-d.com), direct-to-consumer online shop watanabe-wheels.com, domestic aftermarket parts retailers (Car Port Maruzen, Craft, Fuji Corporation), and overseas store partners spanning the US, EU, Canada, and Malaysia. Customer segments include racing teams and drivers (GT, D1, Formula), individual automotive tuners and enthusiasts, classic car restoration owners, commercial/light-truck owners (HiAce, Jimny, NV350), and university racing teams — with 15 Japanese university teams sponsored in the All-Japan Student Formula competition. Pricing per wheel ranges from ¥37,000 to ¥120,000, with set-level custom offset, PCD, hub bore, and color options adding incremental fees.
