1stkey.co.jp is a regional real estate brokerage website operated by First Key Co., Ltd. (Japan), focusing on property rental and sales information services for core areas including Sasazuka, Shibuya-ku, Tokyo and the surrounding Shinjuku-ku. It holds an official Japan宅建 license and operates as a compliant local real estate agency.
The core function of the website is to publish and allow filtered searches for rental and resale properties listed by the agency. It supports precise filtering by location, rent budget, floor plan, and special conditions (free agency fee, zero key money, pet-friendly, close to subway station, etc.). It also offers online inquiries, in-store appointment booking, property search requests and other services, plus a dedicated entry for real-time property search, with new listings updated daily. The website's current main advantage is that it offers a large number of rental properties with free agency fees and zero key money, lowering the initial move-in cost for tenants.
The website can be accessed directly from China. The entire site uses a Japanese-only interface with no Chinese support, and is only intended for users who are proficient in Japanese and have housing needs in the Tokyo area.
Advantages: detailed property information, timely updates, clear discount terms, and intuitive filtering logic. Disadvantages: service coverage is limited to small local areas of Tokyo, no multilingual support, and some fee rules require offline consultation. It is suitable for Japanese-proficient users who plan to look for rental housing or invest in real estate around Shinjuku and Shibuya, Tokyo. Domestic users who plan to move to Japan for housing can also use this site to get an initial understanding of the local property market.
