会社概要Company profile ROMS is a robotics startup providing automation solutions centered on high-performance compact automated storage systems for logistics warehouses and factories. (*More detailed information is available on our corporate site (https://roms.inc/recruit).)

At sites such as warehouses and factories, issues including labor shortages, growing EC demand, fluctuations in shipping volumes, and the effective use of limited space are becoming increasingly serious.

Meanwhile, the current automated warehouse market has been dominated by major companies with large-scale facilities costing several hundred million to several billion yen, putting them out of reach for the mid-sized and small companies that originally need automation. ROMS is a startup founded in 2019 to change this very structure.

Built on the compact design technology and intelligent transport technology cultivated through the development of ultra-compact unmanned stores, our founding business, we deploy automated warehouse systems with an uncompromising commitment to "Made in Japan, fully in-house." With a domestically produced automated warehouse system that enables a small start, we are presenting a new option to the industry as an automated warehouse that can be introduced even at small and mid-sized sites that have not previously been targets for automation.

In 2023, we began full-scale expansion into the logistics warehouse automation field. Adoption has progressed among major domestic logistics operators including Seino Group and NTT Logisco, and the systems are currently in operation at several dozen locations. As "revenue-generating assets in operation, not demos," we continue to prove their value at actual logistics sites, and adoption at manufacturers' factories and warehouses is also progressing.

From 2025 onward, we also entered the U.S. market and established ROMS USA, Inc. (Delaware). Deployment projects in the U.S. are also underway. Domestically, we have built collaborative relationships with major material handling manufacturers and system integrators, further accelerating our domestic expansion.

Furthermore, in August 2026 we announced a next-generation automated warehouse using autonomous lifting robots, expanding the range of irregular spaces and diverse layouts we can accommodate as an automated warehouse that can start with a single bot.
