What this article shows

Recalculated from the official API's 2020 figures, Tokyo's 23 wards have the highest tertiary-sector employment share at 85.5%, followed by Chiba City at 82.1% and Kawasaki at 81.9%. Because the headcounts and ranking in the original article did not match the same official table, all six cities have been standardized to the same indicators.

From Saitama City's 77.0% to Kawasaki's 58.2%, a gap of about 19 points

The tertiary-sector shares are 85.5% in Tokyo's 23 wards, 82.1% in Chiba City, 81.9% in Kawasaki, 81.1% in Yokohama, 81.0% in Saitama City, and 76.8% in Sagamihara. These shares were recalculated using the sum of employment in the primary, secondary, and tertiary sectors as the denominator.

Yokohama and Kawasaki also have large numbers of secondary-sector workers, so service-sector expansion coexists with manufacturing and construction. The share alone does not determine the strength of a city's economy.

Differences between administrative/commercial cities and mixed industrial cities create the ranking

Reading the regional background

Saitama City has commerce and transportation in Omiya and administration and education in Urawa, while Sagamihara and Chiba City also have large shares of prefectural-capital, business, and everyday service functions. Tokyo's 23 wards have an overwhelming number of tertiary-sector workers, but the table also shows about 1.33 million secondary-sector workers, putting its share in fourth place.

Yokohama and Kawasaki retain substantial waterfront industry, construction, logistics, and R&D, which lowers the tertiary-sector percentage. A higher tertiary-sector share is not a ranking of urban sophistication; it reflects differences in specialization and industrial diversity.

How to read these figures

Important notes

Scheduled monthly wages do not include bonuses or overtime pay. This table alone also does not show differences in industry composition, company-size composition, or occupational mix.

The article is organized primarily around published statistical figures. Numerical values directly observable in the statistical tables should be distinguished from interpretations of background factors.

Summary: Saitama leads in service-sector share, while Kawasaki and Yokohama are mixed-industry cities
