What Sealive does

Sealive, Inc. (株式会社シーライブ), founded in February 1995 in Niihama, Ehime Prefecture, Japan, was a privately held hardware and firmware engineering firm that operated two distinct business divisions from a single headquarters. The System Engineering Business delivered consignment-based design of high-reliability electronics for space and industrial customers, including onboard circuit design, FPGA SpaceWire logic (compliant with ECSS-E-ST-50-12C), DC-DC/DC-AC converters, and a proprietary MCP high-voltage 4-output power supply (5 kV DC, 200 kHz switching) used in JAXA/ISAS observation satellites such as SPRINT-A/EXCEED, GCOM-C and ASTRO-H. Customers on this side included Sumitomo Heavy Industries, Symax, SEIKEN and PHC Corporation. The Life Science Business was built around Biovector®, a proprietary complex gas that the company describes as the only technology in the world that decomposes nucleic-acid (DNA/RNA) structures in the gas phase. Biovector® underpins the steriXcure GE100S Decontamination Gas Generator and the newly introduced compact steriXmini system, plus the setriX nucleic-acid decontamination service line, sold to pharmaceutical, laboratory, animal-research and regenerative-medicine customers with a Sterility Assurance Level of Log10⁻⁶ and 99.994% / LRV4.20 reduction of SARS-CoV-2.

The company monetized through a mix of one-time hardware sales, project-based decontamination installation services, and contract system-engineering engagements; pricing is quote-based with no public list, and customers are routed through bilingual Japanese/English inquiry forms on the corporate website. Go-to-market relied on direct enterprise sales supported by a heavy trade-show cadence (co-exhibiting with parent Mito Kogyo at Regenerative Medicine EXPO, PharmaLab EXPO, JALAS, JAET and Medical Creation Fukushima), Nature Index earned media, downloadable technical PDFs, and standard digital marketing infrastructure (Google Analytics, Mailchimp/AWeber/GetResponse). The technology base has been validated externally via AMED funding (2021) for novel-coronavirus countermeasure R&D, ISO 9001-based QMS, Ehime Sugo-waza and Niihama Manufacturing Brand certifications, and the 2022 Shikoku Industrial Technology Award for steriXcure.

As of October 1, 2025, Sealive was merged into Mito Kogyo Corporation (水戸工業株式会社) and continues to operate as the newly established Ehime Electrical and Electronic Design Center of Mito Kogyo, with founder-CEO Yasushi Suzuki serving as Center Director and Ryuzo Narita as Representative Director of the surviving parent.

Core offering

Sealive designs, manufactures and sells gas-phase nucleic-acid decontamination systems (steriXcure GE100S and steriXmini) powered by its proprietary Biovector® complex gas, which decomposes DNA and RNA structures to deliver SAL = Log10⁻⁶ sterility and 99.994% / LRV4.20 reduction of SARS-CoV-2 in laboratory, pharmaceutical, clean-room and animal-facility environments. Alongside this Life Science line, the company delivers contracted space-grade hardware, firmware and PCB design services — including DC-DC converters, SpaceWire FPGA logic and 5 kV DC MCP high-voltage power supplies — for JAXA/ISAS scientific-satellite programs such as SPRINT-A/EXCEED, GCOM-C and ASTRO-H/NeXT.

Product overview

Sealive (株式会社シーライブ), now operating as the Ehime Electrical and Electronic Design Center of Mito Kogyo Co., Ltd. (水戸工業株式会社) following an October 1, 2025 corporate merger, runs two distinct business divisions from its base in Niihama, Ehime Prefecture. The Life Science Business is built around the proprietary Biovector® nucleic-acid-degrading gas-phase technology and is commercialized primarily through the flagship steriXcure GE100S Decontamination Gas Generator, the newly introduced next-generation steriXmini DNA-free Decontamination System, and the setriX Series Nucleic Acid Decontamination Service — together forming an integrated hardware-plus-service offering for sterilization, DNA-free environment regeneration, viral clearance, and oxidative deodorization. The System Engineering Business complements this by providing space-grade hardware design, embedded software/firmware development, and printed circuit board design services, with a proven track record on JAXA/ISAS observation satellites. The two divisions are housed within the same electronics-engineering organization and share underlying competencies in electronic circuit design and embedded control, while targeting fundamentally different end markets (life-science laboratories and cleanrooms vs. space and industrial electronics).
