What LDK does

STELLAR FORCE, Inc. (formerly LDK Co., Ltd., renamed June 3, 2024) is a Japanese corporate housing intermediary founded in 2003 in Suita City, Osaka, and now headquartered in Tokyo. The company operates a single-window model for arranging monthly mansions, weekly mansions, and hotels on behalf of corporate clients managing long-term business travel, training programs, and employee relocations. Its core product, MONTHLY BANK, aggregates inventory from 200+ monthly mansion operating companies and hotel partners covering 700,000+ rooms nationwide, and is delivered through a web platform (monthly-bank.jp) that consolidates search, proposal, contracting, and billing into a single corporate relationship. As of April 2026, the platform reports 800+ corporate clients and 12,000+ transaction cases. The company also operates two complementary services: 好きな家に帰ろう, a corporate housing mediation service for relocations, and remple, a subscription-based furniture and home appliance rental service for single assignees and employees transitioning from company dormitories.

The business model is a transaction-fee intermediary: revenue is earned through brokerage commissions and spreads on accommodation arrangements (with monthly billing under corporate master agreements, including post-payment and installment options), supplemented by recurring subscription revenue from remple. As of January 2026, the company employs 64 staff including part-time workers, operates from Tokyo and Osaka offices (the Nagoya office was closed August 31, 2025), and is privately held with ¥100M registered capital and no venture funding. Distribution is hybrid: direct B2B sales by Tokyo and Osaka sales teams to mid-to-large enterprises, supplemented by channel partnerships with corporate housing management agencies that outsource their monthly mansion arrangements to STELLAR FORCE. The company is not cash-flow constrained in a venture sense but is not pursuing rapid external-funding-driven scaling either.

The technology stack is a web-based SaaS-style aggregation platform with self-serve search and request forms rather than a deep technical moat; the April 2025 appointment of a CTO with prior experience at a publicly listed engineering organization signals intent to upgrade technology capability, though no AI/ML capabilities, mobile apps, or APIs are publicly disclosed.
