What Replus Co. does
REPLUS Co., Ltd. is a small Japanese architectural design firm established in February 2018 and headquartered in Iwami Town, Tottori Prefecture. The firm delivers integrated architectural design, renovation, construction, interior design, consulting, and real estate brokerage services to individual homeowners, small/medium business owners, and hospitality clients primarily in Tottori Prefecture and the surrounding San'in region of western Japan. Its design approach is grounded in a 'subtraction design' / 'Less Is More' philosophy combined with a domain specialization in coastal architecture that uses local materials such as baked cedar (焼杉), reinforced concrete walls, and rafter structures to withstand wind and salt exposure. The firm employs 1–10 staff and holds multiple Japanese professional licenses, including Class 2 architect office, construction, and real estate brokerage registrations, enabling a one-stop delivery model.
Underlying technical capabilities center on spatial composition techniques that blur interior and exterior boundaries through large overhanging eaves, continuous openings, and terrace-based designs intended to integrate buildings with natural coastal landscapes over time. Signature projects include the Kugami Terrace Sunset Cafe & Small Gallery, the aperitio 2023 residence, and THE OFFICE 2024 workspace concept. The firm operates a project-based professional services model, monetizing architectural design fees, construction contracting, consulting fees (including financing and government-subsidy advisory), and real estate transaction commissions, with consultation-driven sales (including free initial consultations) and no publicly disclosed pricing.
The go-to-market relies on direct engagement with clients via phone, email, LINE, and in-person meetings, supplemented by a portfolio-led website, organic social presence on Facebook, Instagram, and Houzz, a content-marketing blog with 54+ posts, and earned media coverage. Replus has accumulated three consecutive years of international design award recognition (A' Design, iF, Red Dot, LICC, IDA, LIV Hospitality Design Awards) for 2024–2026 and has been featured alongside world-renowned architects Kengo Kuma, Kazuyo Sejima, and Hiroshi Naito in ELLE DECOR. The company is privately held, founder-owned and led by CEO and Chief Designer Tomohiro Araki, with no disclosed external funding rounds.
