Career Reveal, an open infrastructure for human capital data operated by Fperi Inc., has cross-referenced and visualized the average annual salaries and average monthly overtime hours of five major companies in the electronic components and devices industry (Keyence, TDK, Murata Manufacturing, Nidec, Kyocera) based on primary information such as securities reports, integrated reports, and sustainability reports, making them comparable.

The electronic components and devices industry, which supports smartphones, EVs, and IoT devices, often has a preconceived image of "high income." However, for company research during job hunting and career changes, it is crucial to understand not only the salary but also "how compensation is structured based on work style (e.g., performance-based, long-term stability, clear separation of work and private life)." This release organizes the differences in "earning and working styles" of the five major companies from both salary and overtime perspectives.

*The data for each company published in this release primarily refers to the latest disclosures (FY2025), but for companies without FY2025 disclosures, the most recent disclosures (FY2024) are referenced.

Survey Results Summary

・ The average annual salary of the five major electronic components and devices companies ranges from 6.94 million yen to 20.39 million yen, a maximum difference of approximately three times within the same industry. Keyence (20.39 million yen) is at the top, maintaining one of the highest levels among listed Japanese companies at the young average age of 34.8 years.

・ The other four companies (TDK 8.30 million yen, Murata Manufacturing 8.03 million yen, Nidec 7.60 million yen, Kyocera 6.94 million yen) range from 7.00 million to 8.30 million yen, which is high compared to the manufacturing industry as a whole. TDK saw a +0.47 million yen increase year-on-year, and Nidec +0.34 million yen, indicating a continuing wage increase trend.

・ Overtime hours for the two companies disclosing FY2025 data (Kyocera and Murata Manufacturing) average 14.35 hours per month. With Kyocera (13.1 hours), Murata Manufacturing (15.6 hours), and Nidec (20.1 hours, FY2024), overtime is managed to a maximum of about 20 hours per month, suggesting a reality where "high income = demanding work" is not necessarily true.

・ The industry average for overtime hours has decreased for three consecutive years from 19.97 hours in FY2023, which can be interpreted as an indication of "improved productivity per hour" due to the penetration of DX and flextime systems.

・ TDK and Keyence do not disclose overtime hours. Keyence explicitly states in its disclosure materials "prohibition of taking work home on weekdays and work-related communication on holidays," suggesting a model that pursues overwhelming productivity within working hours.

Average Annual Salary Ranking (Based on Latest Disclosures)

Created by Career Reveal based on each company's securities reports, integrated reports, sustainability reports, and ESG data books.

1st Keyence Corporation: 20.39 million yen (Average age 34.8 years / Average length of service 11.1 years)

2nd TDK Corporation: 8.30 million yen (43.2 years / 17.2 years)

3rd Murata Manufacturing Co., Ltd.: 8.03 million yen (40.1 years / 14.1 years)

4th Nidec Corporation: 7.60 million yen (41.7 years / 12.6 years)

5th Kyocera Corporation: 6.94 million yen (40.0 years / 15.7 years)

▼ Career Reveal Editorial Department's Analysis (Annual Salary) ▼

From this data, a tendency for "higher annual salary" to correlate with "younger average age and shorter length of service" can be observed. Keyence's 20.39 million yen is sourced from its high-gross-profit structure due to its fabless (no factory) and direct sales system, achieving high compensation with a young workforce averaging 34.8 years of age and 11.1 years of service.

On the other hand, the other four companies—TDK, Murata Manufacturing, Nidec, and Kyocera—range from 7.00 million to 8.30 million yen, but have longer average lengths of service (12 to 17 years), suggesting a lifetime income model where employees earn high salaries stably until retirement. This indicates a clear difference in compensation philosophy within the same industry, whether one aims to "earn explosively from their 20s" or "build a long-term stable high income."

Overtime Hours (Based on Latest Disclosures)

Created by Career Reveal based on each company's securities reports, integrated reports, sustainability reports, and ESG data books.

・Kyocera Corporation: 13.1 hours/month (Paid leave acquisition rate approx. 80%)

・Murata Manufacturing Co., Ltd.: 15.6 hours/month (Paid leave acquisition rate approx. 76%)

・Nidec Corporation: 20.1 hours/month (Paid leave acquisition rate approx. 73%)

・TDK Corporation: Not disclosed (Paid leave acquisition rate approx. 73%)

・Keyence Corporation: Not disclosed (Paid leave acquisition rate not disclosed)

(Reference) Average of 2 companies disclosing FY2025 data: 14.35 hours/month

▼ Career Reveal Editorial Department's Analysis (Overtime) ▼

The average of 14.35 hours/month for the two disclosed companies is significantly lower than the all-industry average (approx. 18-20 hours), meaning the image of "electronic components industry = demanding work" is not supported by primary data. Kyocera, in particular, maintains an extremely low level of 13.1 hours, which can be attributed to the results of operational efficiency improvements through office reforms such as flextime and free-address systems. The industry's overall overtime hours have decreased for three consecutive years from FY2023 (19.97 hours → 16.63 hours → 14.35 hours), suggesting that DX promotion and the penetration of super flextime systems contribute to improved productivity per hour.

TDK and Keyence do not disclose overtime hours, but TDK has introduced a super flextime system without core hours and a remote work system, while Keyence explicitly states "prohibition of taking work home on weekdays and work-related communication on holidays" in its disclosure materials.

Career Reveal's Comprehensive Analysis

Career Reveal's analysis shows that the five major electronic components and devices companies have average annual salaries ranging from 6.94 million to 20.39 million yen, a maximum difference of approximately three times, clearly demonstrating "individuality in compensation design" even within the same industry. On the other hand, the average for the two companies disclosing overtime (FY2025) is 14.35 hours per month, significantly lower than the all-industry average, suggesting that "high income = long working hours" is not a simple equation.

Keyence's model of "high annual salary × undisclosed overtime × clear separation of work and private life" particularly stands out as a compensation design based on "overwhelming productivity within working hours," indicating a corporate culture with a different philosophy of work than the other four companies. It is important to note that non-disclosure of overtime hours does not necessarily mean long working hours; the disclosure method itself reflects a part of the corporate culture.

In future company research, it is organized that looking at not only the annual salary level but also "how compensation is structured (performance-based or long-term stable)" and "transparency of working hour management" as a set will lead to reduced mismatches.

Survey Overview

・ Survey period: Collected and organized in March 2026, based on the latest disclosure materials published as of March 2026.

・ Survey institution (survey body): Career Reveal (Fperi Inc.)

・ Survey targets: A total of 5 companies: Keyence, TDK, Murata Manufacturing, Nidec, Kyocera.

・ Number of valid responses (sample size): 5 companies.

・ Survey method (aggregation method, calculation method): Based on primary public information such as each company's securities reports, integrated reports, sustainability reports, etc., descriptions regarding average annual salary and average monthly overtime hours were collected and organized, and cross-comparison was conducted within a comparable range. Since the definition of disclosure indicators, scope, and granularity may differ among companies, aggregation and description were performed taking these points into consideration.

・ Information sources: Securities reports, integrated reports, sustainability reports, ESG data books, etc. (primary information).

Notes

*Annual salary data is based on the latest disclosures for FY2024 for Nidec only, and FY2025 for the other four companies.

*Overtime and paid leave acquisition rate data are based on the latest public information for FY2024 or FY2025.

*The industry average overtime hours (14.35 hours) is the average of the two companies (Kyocera and Murata Manufacturing) that disclosed overtime hours for FY2025. Nidec's FY2024 data (20.1 hours) is not included, and the simple average of the three companies would be 16.27 hours. TDK and Keyence do not disclose this information, so it does not represent the average for all five companies.

*The all-industry average annual salary (8.57 million yen) is the average for companies registered with Career Reveal (TOPIX Core30 / Large70 / Mid400 [before revision in October 2025]) as the population. This differs from statistics based on all Japanese companies (including unlisted companies).

*TDK and Keyence do not disclose overtime hours, so the cross-comparison of "annual salary × overtime" depends on the disclosure status.
