Tanizawa Sogo Appraisal Co., Ltd. (株式会社谷澤総合鑑定所, operating as "Tanikan") is a Japanese professional real estate and asset valuation firm founded on February 1, 1967, headquartered in a dual-headquarters structure spanning Tokyo (Akasaka Intercity) and Osaka (Nakanoshima Central Tower) with five regional branches (Nagoya, Sendai, Kobe, Hiroshima, Fukuoka) for nationwide coverage. The firm employs 195 full-time and contract staff, including 89 licensed real estate appraisers (不動産鑑定士) as of July 1, 2026 — among the largest credentialed pools in Japan's independent appraisal sector — plus ASA-certified asset evaluators, first-class architects, and compensation consultants. It operates three wholly-owned subsidiaries: Union Research (building evaluation, engineering reports, est. 1969), T-MAX (real estate market research, est. 2001), and Japan Hotel Appraisal (hotel/resort valuation, est. 2006).

The company's core services span real estate appraisal (office, residential, logistics, commercial, hotel, senior, hospital); movable property and infrastructure valuation including renewable energy facilities (solar, wind, biomass, battery storage) with an ~470MW cumulative solar valuation track record; corporate and business valuation for M&A and financial reporting (including PPA and impairment testing); urban redevelopment consulting and statutory compensation calculation; CASBEE environmental building certification (authorized by IBECs since December 2021 for CASBEE Building, Real Estate, and Wellness Office); and international asset valuation delivered through the Valuation Research Group (VRG) global alliance joined in November 2017, spanning 1,300+ professionals across 60+ countries. Revenue mechanics are project-based professional services fees (not publicly disclosed), with the GTM motion being direct enterprise field sales to institutional clients — J-REIT investors, power companies, real estate companies, securities firms, banks, and local governments. The firm maintains ISO 27001 certification (since June 2010), publishes an extensive research library (19 analyst reports, 10 logistics market reports, biannual real estate market statistics, regional Tanikan Reports, renewable energy investor surveys), and applies LLM-based sentiment analysis and satellite data as analytical augmentations within its market monitoring practice.
