Earth Support Co.

What Earth Support Co. does

Earth Support Co. is a privately held Japanese care services company headquartered in Tokyo (Shibuya-ku Sasazuka area), founded in 1996 and led by President Moriyama Noriaki. The company operates as the largest provider in Japan of visiting bath (訪問入浴) services — in which trained personnel transport specialized bathing equipment to clients' homes to provide assisted bathing for elderly and disabled individuals — and reports a 93.9% customer satisfaction rate for this core service. It employs between 5,001 and 10,000 staff across a network of 340 offices covering all 47 prefectures of Japan.

The company runs an integrated care platform spanning 25 service types. Revenue is generated across multiple streams: long-term care insurance services (the largest), facility-based care, private-pay supplementary care, sales/rental/lease of care-related products, event and venue setup services, and contracted municipal and corporate services. Pricing and reimbursement are anchored primarily in Japan's public long-term-care-insurance framework, with private-pay and corporate contracts providing supplementary recurring and project-based revenue.

Earth Support pursues a hub-and-spoke growth model combining organic office openings (including a 2025 Okinawa office), acquisitions (Carewell Anshin in 2020-09, Nissho Kikaku in 2021-04), and strategic partnerships (Junkang Life Insurance in 2019-09, Panasonic Appliances China in 2026-01). It also operates an overseas subsidiary, EARTH ONE, in China since 2016, representing its primary international footprint.
