¥970,000 below Tokyo but almost identical to Yokohama
Kawasaki's ¥4.21 million is 81.3% of the ¥5.18 million figure in Tokyo's 23 wards, a gap of ¥970,000. The difference from Yokohama's ¥4.20 million is only ¥10,000, while the gap with Saitama City's ¥4.07 million is ¥140,000.
Kawasaki also had the highest household income among the six cities, but taxable income is measured per individual taxpayer rather than per household. Because the populations measured by the two statistics differ, similar rankings do not mean the indicators measure the same thing.
A double effect from Tokyo workers in Musashi-Kosugi and local R&D employment
Musashi-Kosugi in Nakahara Ward, Miyamae Ward, and Asao Ward are home to high-income residents commuting to central Tokyo on the Toyoko, Den-en-toshi, and Odakyu lines. An influx of dual-income households in their 30s and 40s into redeveloped condominiums has raised average resident income.
Kawasaki also has high-value employment within the city, including Fujitsu in Nakahara Ward, NEC- and Toshiba-related operations around Saiwai Ward, and JFE Steel and Mitsubishi Fuso in Kawasaki Ward. The ¥4.21 million figure can therefore be understood through both residents' Tokyo earnings and the city's own industrial base—not proximity to Tokyo alone.
How to read these figures
Household income may include income other than wages. It is also calculated for households with two or more members and therefore does not show the situation of one-person households.

Summary: Kawasaki ranks second because residents can earn in Tokyo and in the city itself
Kawasaki's taxable income of ¥4.21 million reflects both Tokyo-commuting residents and local employment in R&D and manufacturing. The difference from Yokohama is only ¥10,000, so the two cities are effectively at nearly the same level.
