H Plus

What H Plus does

H Plus is a Tokyo-based B2B professional services firm founded in April 2013 by Hamaguchi Tsuyoshi (濱口剛士) that delivers integrated solutions across two business domains: Communication and Architecture. The Communication domain encompasses Branding (corporate philosophy, CI/VI, brand strategy), Marketing (4P-based integrated marketing planning, events, market research, marketing systems), and Promotion (video, web/app production, graphic and package design, UX). The Architecture domain covers Architectural design (land utilization, concept proposals, basic and implementation design, renovation, exterior design), Interior design (concept, furniture design, coordination, display and event space design), and Construction (building, interior, furniture production, renovation). A seventh offering, Connect, coordinates external partners — including renowned architects, designers, consultants, legal professionals, and real estate firms — to assemble bespoke cross-domain solutions.

The company's core operating methodology is described as a "Design Management" approach that ties architectural and communication design to corporate strategy. Underlying technology is conventional: a first-class architect office registration (Tokyo Governor No. 63260) authorizes the regulated architectural practice; service delivery relies on human creative talent, partner network coordination, and standard digital production tooling (web/app, video, graphic). There is no proprietary software platform, no AI/ML component, and no API or productized technology offering.

The business model is project-based professional services billing to enterprise and mid-market clients, with quote-based, custom pricing. Go-to-market is direct enterprise sales, with inquiries processed through the company website contact form. The company is privately held, registered in Japan with ¥5,000,000 of capital, headquartered at Tri-Seven Roppongi 8th Floor, Minato-ku, Tokyo. MUFG Bank Shinjuku Branch serves as primary banker and Iris Tax Accountant Corporation handles tax advisory. No customers, revenue, headcount, awards, patents, or external funding rounds are publicly disclosed.
