Profile

J-STAR Co. Ltd. is a private equity investment firm based in Japan, established to provide solutions to small and medium-sized companies. Founded in 2006, it has since made over 100 investments, executing more than 10 deals per year recently. The team comprises experienced investment professionals who partner closely with company management to craft and implement strategies aimed at maximizing business value.

The firm primarily focuses on the sectors of manufacturing, healthcare services, beauty and health products, insurance, and legal services. With a strategy centered on selecting the best investment methods, J-STAR builds business strategies in collaboration with corporate partners. They do not commit to specific geography beyond Japan, with asset management focusing on diverse industry verticals rather than geographical expansion. The organization has displayed consistency in investment practices over the years but has not disclosed specific fund sizes.

Notable investments include APO PLUS STATION CO., a CSO for pharmaceuticals; TOKAI TRIM Co., an automotive seat cover manufacturer; ASIRO Inc., which combines online and offline sales strategies in the legal sector; YOKOI MANUFACTURING LTD., a leader in fire hydrant manufacturing; and ITTY, Inc., a D2C beauty products brand.
