ARI

What ARI does

ARI (エイブル総合研究所 / ABLE Research Institute, Limited) is the dedicated research and consulting think tank of ABLE Group, Japan's leading residential rental brokerage with over 50 years of industry history. Founded in July 2003 and headquartered in Akasaka, Minato Ward, Tokyo, ARI operates with a small team (1–10 employees) and produces the proprietary Contracted Rent Index (成約家賃インデックス) — a monthly index tracking actual contracted rental prices for single-occupant units across 11 major Japanese metropolitan areas, based on transaction data from ABLE Group's nationwide brokerage store network. Its primary customers are rental property owners (家主・賃貸経営者), corporate HR departments managing corporate housing (社宅) programs, and general consumers seeking housing lifecycle information.

ARI's core product portfolio consists of research publications and data reports rather than software. The Contracted Rent Index is the flagship product, differentiated from competing rental market data sources because it is built on actual contracted (not listed) rent transactions from ABLE agency stores, covering standardized unit types (1R, 1K, 1DK, 1LDK; 18–40 sqm; building age 5–25 years) with 2024 average rent as the baseline of 100. The institute also publishes semi-annual Station-by-Station Rent Reports (駅別家賃相場レポート) covering 7 major metropolitan areas, a Housing Market Trend Analysis (住宅市場動向分析) authored by academic advisor Professor Yasushi Yoshida of Tokyo University of Economics, and a category-structured library of articles (Owner's Letters / オーナーズレター) covering tax, inheritance, legal compliance, renovation, energy efficiency, and property management best practices. Distribution is primarily through the company website (kurashi-able.jp), which serves as a public content hub and SEO/lead-generation asset for ABLE Group.

ARI's business model is a hybrid of indirect revenue and direct services. Most research outputs are freely accessible, functioning as a content marketing tool that supports ABLE Group's rental brokerage franchise by establishing data authority and generating qualified leads for property owners. Direct revenue stems from contracted research, surveys, and consulting engagements for property owners, corporations, and general consumers, with pricing structured on an inquiry basis via website contact forms (一般お問い合わせ / 企業お問い合わせ). ARI is a wholly-owned subsidiary of ABLE Holdings and its competitive position is structurally tied to ABLE's nationwide brokerage footprint and transaction data pipeline, with no third-party or external investment ownership signals identified.
