Polus Briest Hanakoganei: A New Development of Modern Homes in a Quiet Tokyo Suburb
Polus Briest Hanakoganei is a forthcoming development of 12 detached houses in the peaceful residential area of Koganei City, Tokyo. Sales for this new-build community are scheduled to begin in early April 2026, with occupancy expected from April 2026. This is a pre-announcement advertisement; no contracts or reservations can be accepted until the official sales launch.
The development features a range of layouts from 3LDK to 4LDK homes. Key features include a multi-functional "Stair Living" space that serves as a family hub, generous storage solutions such as an entrance dirt-floor storage area, a pantry, a linen closet, and a walk-in closet. The homes are designed with high ceilings (2.7m in the living room) and large windows for abundant natural light.
All units come standard with a solar power generation system to reduce utility costs. They are equipped with the Eco-One X5 hybrid water heating and heating system, which uses both gas and electricity for efficiency and can save approximately 30,000 yen annually compared to conventional gas heaters. Other premium standard features include a gas-powered clothes dryer ("Kantakun"), underfloor heating, electric shutters for security and weather protection, a smart key system (Rexul Familock), and a stainless steel kitchen (CLEANUP Studia) resistant to mold and odors.
Each home sits on a spacious plot of land over 109.99 m², with building sizes ranging from approximately 87.36 m² to 98.95 m². Most units include two car parking spaces. The development is certified as "Long-Life Quality Housing," which may offer benefits like preferential mortgage rates. The area is governed by the "Hikari no Ienami Agreement," details of which are available from sales staff.
