Reiwa Corporation

What Reiwa Corporation does

Reiwa Corporation (株式会社レイワ・コーポレーション) is a Tokyo-based private company, established in April 2019 as a wholly-owned subsidiary of Daiko Holdings Group. The company operates two distinct business segments. The first is a direct-to-consumer health food and supplement business built around formulations developed in collaboration with Prof. Ota Tomihisa of Kanazawa University, with the flagship product 脳覚 (Noukaku/Brain Up) — an α-GPC-based cognitive support supplement priced at ¥36,000 for a 60-day supply — alongside Wakeup NEO (learning support) and PrimeNMN15000 (NMN anti-aging), distributed via the company's own website, a toll-free phone order line (0120-973-200), and the d-market.jp marketplace. The second segment is a B2B outbound call center outsourcing business providing customer acquisition, dormant customer reactivation, upsell/cross-sell, and telemarketing proxy services to corporate clients in health product e-commerce, cosmetics, sanitation, and lifestyle infrastructure. Both segments operate exclusively within Japan.

The company's technical differentiation in the health food segment rests on access to Prof. Ota's portfolio of 40+ patents covering functional food ingredients (strawberry polyphenols, barley grass, suizenshina) and a "composite formulation" philosophy that deliberately avoids single-compound purification to minimize toxicity and side effects. Several earlier products — 元気の源 (jelly-type supplement, 2019), バリアアップ (Barrier Up immune supplement, 2020), 白雪茶 (skincare tea), and the original 脳覚 (Brain Up) — have been discontinued, indicating active portfolio churn. The call center segment is differentiated primarily by ISO/IEC 27001:2013 ISMS certification (obtained May 2020), which provides information security assurance relevant to clients outsourcing customer data handling.

Revenue is generated through one-time product sales on a cash-on-delivery basis and professional services fees from B2B call center contracts. Distribution combines the company's own e-commerce storefront and phone order system with third-party marketplace presence (d-market.jp) for select SKUs. Marketing has historically been product-page and phone-driven, with a notable 2025 expansion into TV (Miset Smart TV NEO #214), FM radio, YouTube, and SNS, alongside Daiko Holdings group-level visibility through Super GT motorsport sponsorship of the JLOC T-DASH Lamborghini GT3 team. The company is led by CEO and representative director Kaminaga Dai, having succeeded founding director Mukaida Koya, and has undergone two headquarters relocations — most recently in March 2025 to Aomi, Koto-ku, Tokyo. No external funding rounds or institutional investors are disclosed.
