The Harmony

What The Harmony does

The Harmony Inc. (ザ・ハーモニー株式会社) is a Japanese social venture founded on April 6, 2012, by CEO Takahashi Kazuya (髙橋和也), a former fashion designer who returned to his hometown in Fukuoka Prefecture to address Japan's super-aging society challenges. The company operates a dual-division structure: a Care Division runs dementia-specialized integrated facilities under the 'Rocial Community' (ローシャルコミュニティ) brand across three municipalities in the Chikuho region of Fukuoka Prefecture — Iizuka (opened January 2019), Kama (August 2021), and Tagawa (October 2023) — offering a one-stop service combining day service (デイサービス), overnight respite stays, and residential living (リビング). The company also operates an on-site nursery, Rocial Kids (opened September 2019 in Iizuka), to support working parents in its own workforce and embed childcare into the care-employment value proposition.

The company's Technology Division develops and sells 'Daichan' (だいちゃん), an AI-powered dementia communication robot (product page: daichan.life). Daichan engages dementia patients through conversational dialogue combining voice and text modalities, using natural language processing and generative AI to interact with limited human intervention. The company frames Daichan as a solution to Japan's projected shortage of 9.3 million healthcare and nursing care workers by 2050, in the context of 10 million+ projected dementia patients domestically and 130 million globally.

The Harmony's revenue derives from two streams: recurring fees from dementia day services and residential care under the Japanese long-term care insurance system (subscription-style recurring revenue), and hardware sales of the Daichan robot. The company employs approximately 60 staff across both divisions, recruiting from former care workers, career changers, and U-turn/I-turn individuals, and is founder-owned with one disclosed $2.4 million equity round in May 2021 from DOGAN beta and Nishi-Nippon City Bank, plus non-equity support from G-STARTUP in 2019. Its competitive advantage rests on combining operational care expertise with technology development and a vertically integrated facility-plus-nursery model.

Direct peers

• Tsukui Corporation (ツクイ): Major Japanese operator of daycare and residential care facilities with significant dementia care exposure, listed on TSE. Closely comparable in service model (day service + residential living) and multi-region geographic strategy, but at larger scale.

Broad incumbents

• Nichii Gakkan Co., Ltd. One of Japan's largest care service providers offering home care, daycare, and residential services including dementia programs. Comparable in providing integrated care services, but operates at national scale with broader service portfolio.
• SOMPO Care Inc. Subsidiary of SOMPO Holdings, one of Japan's largest care facility operators with hundreds of locations including dementia-specialized group homes. Directly comparable to The Harmony's core dementia care business, but at vastly greater national scale.
• Benesse Style Care Co., Ltd. Operates 'Aria' branded senior residences including dementia care units across Japan. Comparable in offering integrated residential and dementia support services, though much larger and serving urban markets.

Emerging players

• Cyberdyne Inc. Japanese robotics company developing HAL wearable robots and other assistive/eldercare technologies. Comparable to The Harmony's TECH Division (Daichan) as another Japanese player applying AI/robotics to address the eldercare labor shortage.
• SoftBank Robotics Group: Developer of Pepper humanoid robot and other service robotics with eldercare applications. Comparable to Daichan as another Japan-based AI/robotics product targeting the care market, though with much broader application scope.

Regional players

• Yukari Gakuen (緑壽園 / Yukari Group): Japanese care provider operating dementia-specialized group homes and day services in regional markets. Comparable to The Harmony as a smaller, regionally-focused dementia care operator with similar service mix (day + residential).

Others

• AIST (National Institute of AIST) / PARO: Developer of the PARO therapeutic seal robot, the most clinically validated companion robot for dementia patients globally. Directly comparable to Daichan as the established reference product in dementia-specific robotics.
