What MIRAPRO does

MIRAPRO is a Japanese precision industrial manufacturer founded in 1984 and headquartered in Hokuto City, Yamanashi Prefecture, with approximately 750 employees as of March 2023. The company's core competency is vacuum technology, which it applies across three "clean" verticals it explicitly defines: particle-free environments for semiconductor and display manufacturing, contamination-free environments for medical and biotech applications, and ultra-clean vacuum for large-scale scientific instruments. Its product portfolio spans vacuum components (welded bellows, formed bellows, flexible hoses, vacuum piping, high-purity gas piping, vacuum piping parts, vacuum gauges), semiconductor manufacturing equipment assembly (chillers, full equipment lifecycle services), medical device and FA systems, and next-generation energy products (superconducting flywheel storage, hydrogen liquefaction). MIRAPRO holds the top domestic share in vacuum bellows in Japan and a high global share, with its welded bellows supplied to major semiconductor manufacturing equipment makers globally. The company also contributed ultra-high vacuum ducts and vessels to the KAGRA large-scale cryogenic gravitational wave telescope (NAOJ/KEK) and is collaborating with NIMS/JST on what it describes as the world's first magnetic refrigeration hydrogen liquefier.

MIRAPRO monetizes primarily through direct enterprise B2B sales of engineered hardware, supported by an international footprint of wholly-owned subsidiaries and representative offices in the USA (Santa Clara), China (Shanghai), Singapore, India (Bengaluru), Korea, Thailand (Bangkok and Pathumthani manufacturing), Mongolia, Turkey, Taiwan, and Germany. Its go-to-market relies on technical specification-driven quoting rather than published price lists, with secondary distribution of standard parts via the MISUMI Japan B2B e-commerce platform. The company has built an integrated supply chain through five majority-owned subsidiaries consolidated between 2018 and 2022: Toko Electric (medical devices), Shinsei (surface treatment/plating), Chigaki Giken (semiconductor equipment assembly), Puretec (filters and cleanrooms), and Ubiquitous Technologies (IT, software, FA systems). A proprietary AI platform branded MAI (MIRAPRO AI) and an IoT predictive-maintenance platform branded MPE (MIRAPRO Predictive Eye) are bundled into the HAWKAEYE inspection system, with the first commercial product (HAWKAEYE L Series for eyeglass lens inspection) launched in 2022 and demonstrated at MIDO 2026. The company is private, owner-operated by the founding Tsunegane family (Hiroyuki Tsunagane as CEO since 2012; founder Koichi Tsunagane as Board Chairman), with ¥97.5 million registered capital and no public listing or external funding rounds disclosed.
