REsta

What REsta does

REsta (株式会社REsta) is a Tokyo-based Japanese lifestyle solutions company founded on March 6, 2020, originally as 株式会社EPARKくらしのレスキュー and rebranded to its current name on November 1, 2024. Its flagship platform is EPARKくらしのレスキュー (rescue.epark.jp), a two-sided marketplace that connects Japanese consumers needing home emergency services — plumbing, glass repair, locksmith, pest control, and similar trades — with local service providers who pay listing/lead fees; consumers access the platform for free. REsta also operates REsta Plus, a back-office support add-on for listed vendors. Beyond the marketplace, the company runs two niche consumer content properties: ちいくたいむ (chiiku-taimu.com, parenting/childcare content for children from infancy to elementary school age) and もふたいむ (mofu-taimu.com, pet lifestyle content), both monetized through advertising and affiliate links.

The company's third revenue line is R-Optimizer®, a patented B2B HVAC/R energy-efficiency device that uses free electrons to de-cluster refrigerant molecules in cooling pipes, improving heat exchange efficiency and reducing compressor load by approximately 20% on average. R-Optimizer V-21 is offered as a monthly rental at ¥30,000/month with a 10% reduction guarantee, targeted at enterprises with monthly electricity costs above ¥300,000 (supermarkets, care facilities, electronics retailers, cold storage). Documented case studies show reductions of 20-28% across these segments. R-Optimizer sales follow a structured B2B process (inquiry → explanation → on-site survey → reduction simulation → contract → installation) with follow-up outsourced to partner Gracias Co., Ltd. The company's parent is ROY株式会社 (ROY Corporation), holder of the MA-T System® trademark which received the Prime Minister's Award at the 6th Japan Open Innovation Award.

REsta generates revenue from three structurally distinct streams: marketplace commissions on EPARKくらしのレスキュー, advertising/affiliate revenue from owned media (chiiku-taimu and mofu-taimu), and recurring subscription fees from R-Optimizer hardware rentals. Operations are entirely domestic within Japan. The company is privately held, has no public funding rounds disclosed, and maintains a customer-data joint-use framework with EPARK Co., Ltd., iFlag Co., Ltd., BEST Co., Ltd., and Gracias Co., Ltd. as part of the ROY group ecosystem.
