Field reference: the 2025 options and Rokugeisha’s extensions
Japanese survey labels and Rokugeisha’s English translations, with legacy categories retained to preserve earlier responses.
The Cabinet Office of Japan’s human resources survey asks respondents to choose fields connected with their educational background, current work and other aspects of their lives. The first part of this reference reproduces the labels in the 2025 open-data field master, including the examples and explanations in parentheses.
An extension that preserves earlier responses
Survey options differ in their level of detail across years. An earlier response of “Economics,” for example, cannot simply be reassigned to “Econometrics and economic statistics” or “Economic theory” in the 2025 list. The response alone does not tell us which of those subjects the respondent had in mind.
Rokugeisha therefore uses 2025 as a reference while retaining legacy categories that cannot be assigned to a single current category. We call this the “2025-based extended classification.” Broad and narrow categories coexist; responses are neither duplicated nor divided between categories by inference. This is Rokugeisha’s analytical decision, not an official Cabinet Office crosswalk.
The reference contains 314 entries: 300 from 2025 and 14 retained legacy categories. The current network for 2014 and 2025 displays 310 nodes: 298 named current fields and 12 legacy fields. Response categories 299, 300 and 313 are not drawn, nor is entry 312, which was not a separate option in either of those two years.
The English labels are Rokugeisha’s translations, not official Cabinet Office translations. Read them alongside the original Japanese. This page documents the labels and the reason for the extensions; it does not present the detailed crosswalk for every survey year or the mapping to Japanese school subjects.
Version 1 · 1 October 2026
The 2025 survey options
Entries 1–298 name specific fields; 299 is “Other” and 300 is “None.” The description “299 fields” includes “Other” but excludes “None.” This reference retains all 300 entries in the published master list.
