Are you limiting your Tokyo property search to inside the 23 wards? I used to split it the same way myself — inside versus outside the 23 wards. But once I traced the rail network and looked at the data again, that split didn’t always hold up. The 23-ward boundary is an administrative line — price doesn’t always follow it.

Just west of the city center are locations with access to Shinjuku and Tokyo Station that rivals many spots inside the 23 wards. Today’s subjects are Musashino City, Mitaka City, and Chofu City.

Data Reference: Mansion transaction prices are based on the MLIT Real Estate Information Library (Q1-Q4 2025).

Table of Contents

1. Musashino City

Even if you aren’t familiar with western Tokyo, you’ve likely heard the name “Kichijoji”. Musashino City is the absolute powerhouse of the west, home to this famous neighborhood.

Consistently ranking at the top of “places people want to live” in Japan, it combines the massive nature of Inokashira Park with sophisticated commercial districts. Kichijoji Station, where the JR Chuo Line (direct to Shinjuku) and Inokashira Line (direct to Shibuya) intersect, records 376,317 daily passengers. It holds a unique premium brand value that rivals or exceeds core areas of the 23 Wards.

Against Chiyoda Ward (千代田区), the 70㎡ mansion transaction price is 48.6% of Chiyoda levels. Price defense is incredibly strong despite being outside the central wards.

Areas like Nakamachi and Kichijoji Honcho have already surpassed 100万円/㎡. Musashino’s transaction price per ㎡ rose from 74.5万円 in 2021 to 94.8万円 in 2025, a 4-year CAGR of 6.2%. Population forecast 2020→2040: 4.5%.

2. Mitaka City

Look at Mitaka, and it’s easy to see why being a terminal station matters. Mitaka City sits just south of Musashino, offering a quiet, comfortable residential environment. Home to the Ghibli Museum and excellent schools like the International Christian University (ICU), it is highly popular among families who prioritize education and environment.

Its biggest weapon is transport efficiency. Mitaka Station is the starting station for the JR Chuo and Tozai Lines, with 167,532 daily passengers. In a city notorious for morning rush-hour crowds, being able to sit down for a direct ride downtown is a premium hard to quantify.

Against Chiyoda Ward, the price is 42.5%.

Transactions are heavily concentrated in Shimorenjaku (144 cases). The 4-year CAGR is a strong 5.9%. Population forecast 2020→2040: 5.3%.

3. Chofu City

While the previous two cities use the JR Chuo Line, Chofu City is the western transport hub anchored by the Keio Line.

For Tokyo locals, it’s familiar for the historic Jindaiji Temple and the rich nature of the Tama River. From Chofu Station, the Keio Line Special Express reaches Shinjuku in just 15 minutes, with 115,507 daily passengers. Despite this excellent access, its prices are the most realistic among the three cities in this episode.

Against Chiyoda Ward, the price is 33.2%.

Areas like Tamagawa and Somechi offer 70㎡ equivalents in the 3,000万円 range. The 4-year CAGR is a steady 3.6%, population forecast 2020→2040: 4.5%, and annual transaction volume (418 cases) ensures good market liquidity.

4. Comparison Summary

Series Comparison:

It’s impressive that Musashino and Mitaka, despite being outside the 23 Wards, maintain price defense that matches or exceeds outer wards like Kita.

5. Investment and Living Guide

Living Perspective

Musashino City suits families in their 30s and 40s who want childcare access, shopping convenience, and green space together. Being able to walk to the Kichijoji retail district on foot is a rare combination in Tokyo.

Mitaka City is worth a look for commuters who want to cut morning stress. Being a terminal station changes the daily commute experience noticeably. It’s also priced a step below Musashino while sharing the same living area, which stands out on a cost basis.

Chofu City suits those on a tighter budget who want more floor space, or who prioritize natural surroundings like the Tama River. A 15-minute express ride to Shinjuku keeps the commute manageable.

Investment Perspective

Being outside the 23 wards administratively doesn’t diminish investment value. In Japan’s property market, rail access matters far more than administrative boundaries.

Musashino and Mitaka have posted 4-year CAGRs of 6.2% and 5.9% respectively — prices have climbed steadily. Both cities are projected to see population growth of about 4.5–5.3% through 2040, and so far the data points to a fairly stable trend.

Chofu offers a clear price advantage — about 33% of Chiyoda’s level — which gives it a favorable starting point from a yield perspective. It suits stable cash flow and owner-occupancy more than capital gains.

Once again, the rail line explained more than the administrative boundary did. If I were choosing among these three, I’d look at the line and the distance to the station first, and check the ward boundary after.
