South Korean AI Solution Development Company Smartcube Establishes First Japanese Base in Sapporo!

Sapporo City is actively attracting foreign companies, viewing the advancement of Rapidus Corporation aiming for mass production of next-generation semiconductors in Hokkaido and the designation of Hokkaido/Sapporo City as a special zone for finance and asset management as opportunities. In particular, to revitalize the local economy and enhance the international competitiveness of businesses, the city is proactively working on industrial clustering in advanced technology fields such as IT and creative industries, leveraging the city's strengths. With the support of the Sapporo One-Stop Center for Accepting Foreign Companies (STEP), Smartcube, a digital and AI solution development company from Naju City, South Korea, has established its Japanese subsidiary, Onyx Lab Inc., in Sapporo. The company was incorporated on January 30, 2026. The city will support the future business expansion of Onyx Lab Inc., which is expected to contribute to the clustering of the IT and creative industries.

[Comment from Hiroshi Sasaki, Representative of the Japanese Subsidiary] We are pleased to announce the establishment of Onyx Lab Inc. in Sapporo as the Japanese subsidiary of SMARTCUBE Co., Ltd. Due to a connection where the owner of our parent company in South Korea previously studied in Hokkaido, we chose Sapporo, the center of Hokkaido's economy with its rich natural beauty and excellent environment, as our base for our first overseas expansion. We are very encouraged by the presence of the STEP team, who have provided us with various advice and support since the beginning of this establishment, and who have strongly supported our expansion. SMARTCUBE, established in 2017, is a company specializing in the digital twin field. From this land of Sapporo, in collaboration with the local community, we will deliver new value to Hokkaido and the entire nation of Japan.
