What Graphite Design does

Graphite Design is a Japanese manufacturer specializing in carbon fiber golf shafts, founded in 1989 and headquartered in Chichibu, Saitama Prefecture. The company produces more than 80 shaft models across three brands — TOUR AD (flagship, drivers/fairways/utilities/irons), Chichibu (premium lightweight, 40g range, featuring Kuraray Vectran fiber), and RAUNE (hybrids, irons, wedges) — using hand-crafted lamination and winding processes developed in-house at its single Chichibu factory, which has a capacity of 1,000+ shafts per day. The proprietary technology stack relies on exclusive materials including Torayca T1100G and M40X carbon fibers, with specialized reinforcement technologies such as Tourneado Tip, AD Shield, and Sheet Winding Compression Molding (SWCM) supporting both golf and non-golf composite products.

The company operates three primary go-to-market channels: a nationwide network of 500+ authorized golf retailers and workshops spanning all Japanese prefectures, an owned e-commerce store (store.gd-inc.co.jp) supported by an online SHAFT FINDER recommendation tool, and — since September 2025 — a company-operated fitting studio, GRAPHITE DESIGN FITTING BASE, in Asakusa, Tokyo. Revenue is generated primarily through premium-priced shaft sales (entry-level iron shafts from 12,000 JPY up to flagship driver shafts at 69,300 JPY) targeting amateur golfers and tour professionals, supplemented by an OEM industrial composites business serving customers such as HKS (automotive CFRP brace bars), AdamJapan (billiard cue shafts), and ice Magic (speed skating carbon handles). The company also runs an active tour development program in which dedicated staff, including Japan Mid-Amateur champion Takahashi Masaya, translate professional player feedback into product development, and the CEO, Yamada Takuro, has publicly identified overseas market expansion as a strategic priority.

The company employs 101-250 staff, remains privately held with no disclosed institutional investors, and operates solely within Japan. Strategic positioning leans on handmade-in-Japan craftsmanship, exclusive material relationships, deep tour integration, and a growing industrial composites franchise that has won the Composite Highway Award 2024 Grand Prize.

Core offering

Graphite Design designs, handcrafts, and sells carbon fiber golf shafts under three primary brands—TOUR AD (the flagship tour-oriented lineup), Chichibu/秩父 (the premium ultralight sub-brand), and RAUNE (hybrid/iron/wedge-focused). All shafts are manufactured at the company's Chichibu, Saitama factory using proprietary lamination, sheet winding, and composite molding technologies. The company also operates a Composites division that supplies custom CFRP pipes and components for automotive, sports equipment, and industrial OEM customers.

Product overview

Graphite Design is a Japanese manufacturer of carbon fiber golf shafts offering a comprehensive portfolio of three main brands: TOUR AD (the core flagship line of driver, fairway wood, utility, and iron shafts), 秩父 (Chichibu, the premium sub-brand emphasizing ultralight weight from 40g with VECTRAN® fiber technology), and RAUNE (a sub-brand optimized for hybrid/iron/wedge applications using carbon design flexibility). All shafts are handmade at the company's Chichibu, Saitama Prefecture factory. The product lineup spans over 80 models across different weight classes (from ~37g to 115g), flex options (L, R, SR, S, X, TX), and kick point configurations to suit every golfer from beginners to tour professionals. Supporting the product portfolio are direct services including the Asakusa-based GRAPHITE DESIGN FITTING BASE for professional shaft fitting, the SHAFT FINDER online recommendation tool, and the SHIFT the SHAFT educational marketing campaign. The company also operates a Composites business unit applying CFRP pipe manufacturing technology to non-golf industrial and sporting applications.

Broad incumbents

• Mizuno: Mizuno is a Japanese sporting goods manufacturer with a strong domestic golf equipment business (clubs, apparel) and comparable premium Japanese craftsmanship positioning. While not a shaft specialist, it competes for similar Japanese golfers and tour visibility.
• TaylorMade Golf: TaylorMade is a global golf club manufacturer and an OEM customer of Graphite Design (TOUR AD CQ 5-S is listed as a stock custom option on TaylorMade STEALTH GLORE PLUS). As a major golf OEM with broader product portfolio, it is both a partner and an adjacent incumbent in the equipment ecosystem.

Direct peers

• Fujikura Composite America: Fujikura Composite manufactures the Ventus, Motore, and Speeder premium carbon fiber golf shaft lines used widely on PGA and major OEM tours. It is a direct head-to-head competitor in the same premium graphite shaft category as TOUR AD and Chichibu.
• UST Mamiya: UST Mamiya produces the Attas, Recoil, and LIN-Q carbon composite golf shaft lines and competes directly in the premium shaft market used by club fitters and tour professionals.
• Aldila: Aldila manufactures premium carbon fiber golf shafts including the Rogue, Ascent, and NV series. Now operating under Mitsubishi Chemical, it remains a direct competitor in the same product category with comparable tour presence.
• Mitsubishi Chemical (Golf Shaft Division): Mitsubishi Chemical's golf shaft business produces the Diamana, Basileus, and TENSEI carbon shaft lines and absorbed Aldila in 2017. It is the most direct competitor to Graphite Design in premium carbon fiber shafts and also serves industrial composite markets.
• KBS (FST): KBS (Kim Braly Signature) manufactures steel and graphite golf shafts under its own brand and competes for the same club fitter and OEM relationships as Graphite Design, particularly in the iron shaft category where Graphite Design's RAUNE competes.
• True Temper Sports: True Temper Sports produces Project X, Dynamic Gold, and HZRDUS shaft lines (the latter in carbon composites), making it a major direct competitor in premium golf shafts globally with strong tour and OEM presence.
• Nippon Shaft: Nippon Shaft is a Japanese manufacturer of both steel and carbon fiber golf shafts (N.S. PRO, Modus series) with strong presence on Asian tours. It is a direct peer in golf shaft manufacturing with comparable domestic Japanese market positioning.

Others

• Toray Industries: Toray Industries is the supplier of Torayca T1100G and M40X carbon fibers that underpin Graphite Design's premium shaft performance claims. As the upstream carbon fiber manufacturer and a strategic supplier, Toray is an ecosystem participant rather than a competitor.
