Two-or-more-person households in Kawasaki have average annual income of about ¥10.94 million, with about ¥9.75 million in the 30s, ¥12.76 million in the 40s, and ¥13.29 million in the 50s. Three forces support these figures: commuting to Tokyo, the inflow of high-income dual-earner households, and R&D and manufacturing employment inside Kawasaki itself.
Annual income of two-or-more-person households in Kawasaki by age of household head (2019)
| Age of household head | Annual income (¥1,000) | Approx. ¥ million |
|---|---|---|
| Average, all ages | 10,940 | About ¥10.94m |
| 30–39 | 9,752 | About ¥9.75m |
| 40–49 | 12,763 | About ¥12.76m |
| 50–59 | 13,290 | About ¥13.29m |

Income rises by about ¥3.54 million from the 30s to the 50s, then declines
Annual income is ¥9.752 million for ages 30–39, ¥12.763 million for 40–49, and ¥13.290 million for 50–59. The increase from the 30s to the 50s is about ¥3.538 million, showing especially high household income among working-age families.
The figure falls to ¥9.830 million for ages 60–69 and ¥8.449 million for 70–79. Kawasaki's high household income is therefore more pronounced among working households in their 30s through 50s than among older households.
Tokyo commuters in Musashi-Kosugi and high-value-added jobs inside Kawasaki
Musashi-Kosugi in Nakahara Ward, as well as Miyamae and Asao wards, includes many dual-income households in their 30s and 40s who commute to central Tokyo via the Tokyu Toyoko, Den-en-toshi, and Odakyu lines. Rising averages in Musashi-Kosugi should be understood not as every existing resident becoming richer, but partly as the result of higher-income households moving into redevelopment condominiums.
Kawasaki also has high-value-added employment within the city, including Fujitsu in Nakahara Ward, NEC and Toshiba-related facilities around Saiwai Ward, and JFE Steel and Mitsubishi Fuso in Kawasaki Ward. Kawasaki is both a city where people earn in Tokyo and a city where they can earn well locally.
How to read these figures
These statistics cover annual income for two-or-more-person households; single-person households are excluded. Annual income may also include business income, pensions, dividends, retirement payments, and other sources in addition to wages. The figures therefore do not represent working-age salaries alone.
Averages are also affected by household composition. They should be understood as aggregate values for two-or-more-person households rather than as income levels shared by every household in Kawasaki.
Summary: Kawasaki's high household income comes from two strong earning channels among working households
Kawasaki's high household income reflects both high-income dual-earner households working in Tokyo and R&D and manufacturing jobs inside the city. The effect is especially visible among households in their 30s through 50s, with income declining after the 60s.
- Overall average: about ¥10.94 million
- 40s: about ¥12.76 million; 50s: about ¥13.29 million
- The inflow of high-income households into areas such as Musashi-Kosugi lifts the average
- Local employment from companies such as Fujitsu, NEC, and JFE Steel also supports income
