What Faraday Factory Japan does
Faraday Factory Japan LLC, founded in July 2011 and headquartered in Hachioji, Tokyo, manufactures and sells second-generation high-temperature superconducting (2G HTS) tape. The company operates as a subsidiary of the US-based Faraday Group (parent: Faraday 1867 Holdings LLC) since 2022, and runs manufacturing at a new three-story Zama factory in Kanagawa Prefecture, opened April 2024 and ISO 9001-certified in May 2026. Its product portfolio comprises three tape variants: HERMES (the standard 2G HTS tape produced since 2012), Mirai (a next-generation tape introduced in 2025–2026 with Je(20K,20T) exceeding 1,000 A/mm² for 40+ Tesla applications including space magnets), and ELECTRA (a tape variant for power transmission line R&D). The company describes itself as the world's largest HTS producer, with cumulative deliveries of 5,000 km of HTS tape to the nuclear fusion industry as of September 2024.
The underlying manufacturing stack combines IBAD (Ion Beam Assisted Deposition) and PLD (Pulsed Laser Deposition) methods, followed by silver magnetron sputtering and copper electrochemical plating, with machine vision-based quality control. The company holds a technology cooperation with Coherent Corp. (NYSE: COHR), using Coherent LEAP excimer lasers as the industry standard for PLD-based HTS tape manufacturing. This manufacturing stack is positioned to enable zero-carbon applications including compact fusion reactors, low-loss power transmission lines, lightweight wind generators, aerospace magnets, and scientific/medical instrumentation.
Faraday Factory Japan sells HTS tape through direct enterprise sales with quote-based, multi-year contracts. Its primary customer segment is the nuclear fusion industry (e.g., Proxima Fusion, Vision Electric Super Conductors GmbH), with secondary segments in power transmission, renewable energy, aerospace, and scientific/medical devices. Pricing is not publicly disclosed; customers request quotations through the company website. The company has announced a multi-year delivery contract with VESC running through 2027 for a 200,000 Ampere superconducting busbar system at a Hamburg aluminum smelter, and management has publicly stated plans to build the world's largest HTS tape factory to drive unit costs below copper, projecting a billion-sized superconductor market by 2030.

Faraday Factory Japan competitors and assessment
Company assessmentDirect peers
- SuperPower (Furukawa Electric): A US-based 2G HTS wire manufacturer, subsidiary of Furukawa Electric. Direct competitor producing REBCO superconducting tape for fusion magnets, power transmission, and defense applications — overlapping technology stack (IBAD-based) and customer base with FFJ.
- THEVA Dünnschichttechnik GmbH: German manufacturer of 2G HTS (REBCO) tape. Direct competitor focused on European fusion and industrial customers, with a differentiated ISD (inclined substrate deposition) process — competes with FFJ for the same fusion and power transmission accounts in Europe.
- SuNam Co., Ltd. South Korea-based 2G HTS tape manufacturer supplying REBCO wire to fusion, power, and industrial customers globally. Direct competitor in the same product category with overlapping customer segments, particularly in Asian and US markets.
- Fujikura Ltd. Japan-based global leader in 2G HTS (REBCO) tape production for fusion, power and scientific applications. Fujikura is FFJ's most direct global competitor in REBCO/2G HTS wire, competing head-to-head in the same customer accounts and on similar performance specifications.
- Shanghai Superconductor Technology Co., Ltd. (SST): China-based 2G HTS tape producer scaling capacity for fusion, power, and industrial magnets. Direct competitor in the same REBCO tape category, with a strong cost position and growing presence in international fusion programs.
Emerging players
- Tokamak Energy: UK-based compact fusion company that developed HTS tape capability (via acquisition of Ridgway Metals/MetOx). While primarily a fusion developer, it is also a competitor in HTS tape production, positioning vertically in the same supply chain as FFJ.
- SuperOx: Russia-based 2G HTS tape manufacturer supplying REBCO wire to fusion and industrial customers. Emerging competitor with growing capacity and similar product offering; relevant as a marginal alternative supplier in international markets.
Broad incumbents
- American Superconductor Corporation (AMSC): US-based provider of HTS wire and grid-scale power systems. While AMSC has historically focused on 1G (BSCCO) wire and system-level solutions, it is a broader incumbent competing for utility, wind and grid customers that FFJ also targets with its HTS tape.
- Bruker Energy & Supercon Technologies (BEST): Division of Bruker producing low- and high-temperature superconducting materials and systems, including HTS wires and magnets. A broader incumbent with diversified superconductor offerings that overlaps with FFJ's HTS tape market in scientific instrumentation and large-scale magnet applications.
Others
- Coherent Corp. US-listed (NYSE: COHR) laser and photonics company whose LEAP excimer lasers are the industry standard in PLD deposition of HTS tape. Strategic technology partner to FFJ's parent and enabler of the company's scale-up roadmap; included as a critical ecosystem participant, not a direct competitor.
