Arc Project

What Arc Project does

Arc Project (株式会社アークプロジェクト) is a Kumamoto, Japan-based application service provider founded in May 2004 by Eiji Hoshino, who continues to serve as Representative Director. The company builds and operates three mobile-focused cloud services delivered through a dedicated ASP platform: Star Reserve (スターリザーブ), a reservation management system with calendar, customer management, and credit card payment processing supporting salon-type and school-type calendar formats and group-based capacity controls; Star Seven (スターセブン), a carrier email delivery platform specialized for Japanese mobile carrier addresses with high delivery rates and cost-performance positioning; and Star Form (スターフォーム), a self-service form builder for contact, survey, and registration forms. Notable technical integrations include Google Calendar (available from Plan 5000 and above), and the platform is operated as a direct, web-based, self-serve ASP without reseller channels.

The company monetizes via monthly subscription ASP services to Japanese businesses, with a primary horizontal SMB segment and an enterprise customer set spanning entertainment (Shochiku Geino, Horipro), media and broadcasting (Kagoshima Television Broadcasting, Toyama Television Broadcasting), real estate/construction (Toyota Home), financial services (Ricoh Leasing), and government (Nogata City Hall). Distribution is direct through product-specific websites (reserve.star7.jp, star7.jp, form.star7.jp) with a PLG/API-first go-to-market; pricing is not publicly disclosed although Star Reserve underwent a pricing revision effective 2024-02-01 on selected plans. Arc Project has held a Privacy Mark certification under JIS Q 15001 since April 2010 and continues to release iterative product updates to Star Reserve. Operations are concentrated in a single headquarters in Kumamoto City with no disclosed geographic expansion, funding activity, or M&A, consistent with a mature, owner-operated ASP business.

Arc Project's competitive positioning rests on domain specialization in Japanese mobile-carrier email delivery, cost-performance pricing for SMBs, and a compliance posture (Privacy Mark/JIS Q 15001) that supports entry into regulated buyers. The company has historically extended into hardware add-ons (Rapinavi Light, Rapinavi mini, Pit Touch miniS) for mobile membership registration, although no new hardware products have been noted in recent years. AI/ML capabilities are not disclosed in any of the available sources.
