Polus Group's IMS Tanashi Project: A New Residential Community in West Tokyo
Polus Group's IMS Tanashi Project (provisional name) is a forthcoming residential development in Nishitokyo City, Tokyo, offering a total of 13 new-build houses. This is a pre-announcement advertisement, meaning that no contracts or reservations (including provisional reservations) will be accepted until sales officially commence. No measures will be taken to secure application priority. Sales are scheduled to begin in late February 2026.
The development features two distinct blocks, each offering a different atmosphere, blending the warmth of sunlight with the warmth of community. Key architectural highlights include a "Skip DEN"—a multi-level space with a work counter that feels like an extension of the living room—and a "Connect Room" that can serve as a private room or an open extension of the living area, perfect for a kids' space or home gym. Specific unit details are provided: Building 7 has a total floor area of 94.76m² (including a 3.72m² inner balcony), Building 12 is 106.40m² (including a 6.62m² inner balcony), and Building 13 is 103.05m² (including a 5.21m² inner balcony). The project is subject to the "Hikari no Ienami Agreement," where LED exterior lights automatically illuminate at dusk for enhanced safety and beautiful streetscapes.
Standard equipment and facilities include public water supply, Tokyo Electric Power (and others), city gas, main sewerage, car space, exterior landscaping, and a complete set of ancillary equipment. The area is designated as a Category II Height Control District, Quasi-Fire Prevention Zone, and Land Readjustment Project Regulation Area. The building coverage and floor area ratios may be relaxed or restricted based on various conditions such as road access and fire-resistant construction. Completion is scheduled for mid-May 2026 (two units) and mid-July 2026 (one unit).
The property boasts a prime location approximately a 10-11 minute walk from the express-stop "Tanashi" Station on the Seibu Shinjuku Line, providing direct access to Takadanobaba Station in 17 minutes and Seibu Shinjuku Station in 20 minutes. The area is rich with daily amenities within walking distance. An interesting local fact is that Nishitokyo City was formed in 2001 by the merger of the former cities of Tanashi and Hoya, creating a unique blend of suburban residential comfort and convenient city access. The closest major tourist attraction is the historic and beautiful Ghibli Museum in nearby Mitaka City, a must-visit for fans of animation and art.
