■ Highlights of Each Station in the Ranking

[Kasai]
'Proudly holding the undisputed top spot for the 3rd consecutive year'
The greatest appeal is its overwhelming access, allowing direct travel to Otemachi, one of Japan's largest business districts, in about 20 minutes.
The Tokyo Metro, with its high frequency of trains, allows residents to go to the station without worrying about timetables, offering a stress-free experience.
Kasai, where rent can be kept about 40% lower than in Monzen-nakacho, is attractive for its excellent balance between convenience and rent.

[Koiwa]
'The strong station ranked 3rd in 2024 moves up 1 rank'
The town is being upgraded due to ongoing redevelopment.
It is situated in a location where residents can access the Akihabara and Shinjuku areas without transferring, and it also offers easy access to the Tokyo Station area. Although it is convenient as a commuting zone to the city center, the rent is relatively modest compared to areas inside the Yamanote Line.

[Kunitachi]
'The first town designated as an educational district in Tokyo'
Designated as an educational district, its 'calm living environment' is highly supported by parents who hold the decision-making power for students' residential contracts. With universities within walking distance from the station, it is popular among students because part-time jobs, school, and housing are compactly integrated.

[Nishiarai]
'Ranking in with a significant jump from 14th place last year'
Due to the redevelopment of former factory sites such as Nisshinbo, there is an overwhelmingly large number of new and clean rental properties compared to other stations, and its high rate of newly built properties is highly popular. It offers convenient access with mutual direct operations on both the Hibiya Line and Hanzomon Line.

[Musashisakai]
'The second station ranking in from the Chuo Line'
Rapid trains stop here, allowing access to Shinjuku in around 20 minutes. While offering high traffic convenience, the town is equipped with a calm living environment unique to an educational district. Despite being close to the popular Kichijoji area, it is also attractive that one can live there with a median rent of 65,000 yen.

■ Summary: Towns that offer a 'Sense of Value'
Many demographic groups choose rent in the 60,000 to 70,000 yen range, and it can be observed that they select locations by emphasizing the balance between a highly convenient living environment, such as shopping streets near the nearest station, and a quiet residential environment. Furthermore, access to the city center is also considered important, showing a tendency to prioritize stations that offer direct access to major areas in the city center.

■ Extraction Conditions
* Targets single-living properties: 1R, 1K, 1DK, and 1LDK. Since the number of 1K properties is the largest, the rent amount is based on the median value of 1K properties.
* Rent is calculated as the median value including the management fee (common service fee).
* Because the rent is presented as a median value, please view it as a reference value.
* Created based on Able's contract data from January to December 2025. This analysis does not indicate the trends of the entire market.
