Scheduled monthly wages in Gunma rise from ¥239,900 at ages 20–24 to ¥378,000 at ages 55–59. Although Gunma has the lowest all-age average among the seven Kanto prefectures, the prefecture cannot be summed up simply as "low-wage Gunma" once the different local economies are considered, including SUBARU-related industries in Ota and Oizumi and the urban functions of Takasaki and Maebashi.
Scheduled monthly wages in Gunma by age (2023, men and women combined)

Wages rise gradually into the late 50s, then fall by ¥68,700 in the early 60s
Scheduled monthly wages are ¥300,700 at ages 30–34 and ¥352,600 at ages 40–44, then continue rising step by step to ¥378,000 at ages 55–59. The increase from the early 20s is ¥138,100 per month.
At ages 60–64, the figure falls to ¥309,300, a decline of ¥68,700 from the previous age group. The all-age average is ¥326,600, but there is also a substantial gender difference: ¥359,700 for men and ¥264,600 for women. Industrial mix, occupation, and workforce composition all matter when reading the prefectural average.
Published figures by gender
| Age group | Men | Women | Women ÷ men |
|---|---|---|---|
| All ages | ¥359,700 | ¥264,600 | 73.6% |
| 20–24 | ¥248,100 | ¥229,400 | 92.5% |
| 25–29 | ¥286,300 | ¥255,000 | 89.1% |
| 40–44 | ¥387,500 | ¥287,500 | 74.2% |
| 55–59 | ¥426,500 | ¥275,900 | 64.7% |
The table shows a smaller gender gap among younger workers and a widening gap as age increases.
Ota's SUBARU-centered economy is very different from Maebashi and Takasaki
Ota, Oizumi, and the surrounding Ora District are home to SUBARU's Gunma manufacturing operations, including the Main Plant, Yajima Plant, and Oizumi Plant, as well as many related suppliers. Technical and skilled jobs in the auto industry support local incomes, giving the eastern part of the prefecture a wage structure strongly shaped by manufacturing—a true SUBARU company-town economy.
Maebashi, by contrast, has a larger share of public administration, healthcare, and education, including the prefectural government and Gunma University Hospital. Takasaki is a Shinkansen hub with a stronger concentration of commerce and branch offices. The tourism and mountainous areas of Agatsuma and Tone have still different industrial structures. Gunma's prefectural average therefore blends Ota's manufacturing economy, Takasaki's commercial economy, Maebashi's public services, and tourism and agricultural regions. Differences within the prefecture need to be kept in mind.
How to read these figures
These statistics measure scheduled monthly wages and do not include bonuses or overtime pay. They are aggregate values for all industries and both sexes, so the table alone cannot show differences in industry, position, tenure, or employment status.
What can be confirmed from Gunma's published 2023 figures is that wages rise through the late 50s before declining at ages 60–64, and that the gender gap widens with age. Industry-specific and employment-status data should also be examined when considering the background factors.
Summary: Beneath Gunma's prefectural average is a higher-wage manufacturing area centered on SUBARU
Even though Gunma's all-age average is relatively low within Kanto, the manufacturing economy of Ota and Oizumi has a different wage structure. Job seekers should not judge the prefecture only by a single average, but should distinguish between the auto industry in eastern Gunma, public administration and healthcare in Maebashi, and commerce in Takasaki.
