Comcraft

What Comcraft does

Comcraft (株式会社コムクラフト) is a privately held Japanese electronic components trading company founded in 1976 and headquartered in Tokyo, importing high-voltage, high-frequency, high-power, and high-reliability components from U.S., European, and Taiwanese manufacturers and reselling them to domestic Japanese first-class manufacturers. Its product portfolio spans relays and switches (vacuum, electromechanical, reed, solid-state, microwave, and aerospace-grade hermetic), capacitors (ceramic, film, oil, vacuum, mica, high-voltage disc), cables and connectors, X-ray/sensor equipment, high-voltage resistors, and MIL-spec parts, with key distribution partnerships including TELEDYNE RELAYS, TELEDYNE COAX, Pickering, KILOVAC, BEHLKE, CII, HARTMAN, COMET, HITANO, High Energy Co., and KNOWLES-CDE. Target end-markets are communications/microwave, medical equipment, semiconductor manufacturing equipment, and aerospace/defense, with a specific Total Supply Service for hard-to-source and discontinued parts (including Murata substitute ceramic disc capacitors) and semiconductor fab maintenance parts.

The company's business model is sales-led and partnership-driven: technically trained sales engineers propose products directly to enterprise customers, while a separate channel-partner relationship with U.S. electronic component specialty trading companies supports a New York–Los Angeles–Tokyo–Osaka network for rapid information and stable delivery. Revenue is generated through one-time product sales margins on imported components plus attached professional services (incoming and pre-shipment inspection, failure analysis, and technical support) performed at the in-house Technical Center established in 1983. Pricing is quote-based and not publicly disclosed, with multi-year contract cadences. The firm holds ISO9001:2015 (since 2003) and KES Environmental Management Standard (since 2005) certifications, has 11–50 employees, and is led by Representative Director Daisuke Ichitsubo (市塚大介). No revenue, funding, or financial details are publicly disclosed.
