The firm manages a series of domestic and offshore investment funds, with cumulative fundraising of roughly 550 billion yen across six fund generations as of its own disclosures, and it has completed dozens of investments in Japanese companies. Polaris focuses on management buyouts, take-privates, carve-outs of subsidiaries and business divisions from large corporations, and owner business-succession transactions. Its stated investment themes span technology and manufacturing with globally applicable patents, healthcare and welfare businesses driven by aging and social-security needs, IT, services and logistics, and consumer goods and retail with strong Japanese brands and global potential. It has also expanded into growth buyouts, particularly in healthcare and technology. The firm operates a Tokyo head office and an Osaka branch, and through its Singapore subsidiary Polaris CG Singapore Pte. Ltd. it supports the global expansion of portfolio companies. It signed the Principles for Responsible Investment (PRI) in 2016 and has established ESG and DX promotion committees. Its portfolio has included companies such as SMILE, Drug Eleven, Kyusai, Top Tour, Ekitan, Nihon Oil Pump, Aucnet, Works Applications, Sosei World, BAKE, FCNT, O-net, HITOWA Holdings, i-PRO, Sogo Medical, Geotechnologies and others. Polaris has also faced notable difficulties, including the bankruptcy of portfolio company Fusen Usagi in 2013 and the civil rehabilitation filing of FCNT in 2023, as well as insider-trading allegations against a former employee that led to prosecution in 2022 and the publication of preventive measures in 2023. The firm remains an active mid-market private equity sponsor in Japan.
