### Topic
Tax Review Office Personnel Undisclosed: Transparency Issue

### Summary
The 'Tax Special Measures and Subsidies Review Office' within the Cabinet Office's Administrative Reform Promotion Secretariat has been established with a clear purpose and is reported to operate with approximately 30 staff. However, the provided documents do not identify the specific names of the personnel, their concurrent governmental positions, or their terms of service. Consequently, the requested list of past and present staff cannot be furnished based on the available information.

### Body
The 'Tax Special Measures and Subsidies Review Office' was established on November 25, Reiwa 7 (2025), within the Cabinet Office's Administrative Reform and Efficiency Promotion Secretariat, with the objective of promoting the proper optimization of tax special measures and subsidies (Source 7). This initiative, also referred to as 'Japan's DOGE,' aims to reduce administrative waste (Source 4). The office is reported to operate with a team of approximately 30 individuals (Source 6), and it has been suggested that staff may hold multiple concurrent positions (Source 8). However, the provided sources contain no descriptions that would allow for the identification of individual staff members' names, their specific concurrent governmental positions, or their terms of service within this office. Related information mentions attendees of relevant ministerial meetings concerning this review, including Sanae Takaichi (Minister for Economic Security, Minister of State for Economic and Fiscal Policy, Minister of State for Science and Technology Policy), Satsuki Katayama (Vice Minister of Finance, or referred to as Minister of Finance), Masanobu Ogura (Deputy Chief Cabinet Secretary), and Hideki Murai (Deputy Chief Cabinet Secretary) (Source 5). These individuals are not listed as direct staff members of the 'Review Office' but are rather indicated as attendees of related meetings or as ministers/vice-ministers overseeing this initiative. Therefore, the requested 'list of past and present staff, their specific concurrent governmental positions, and their terms of service' cannot be provided at this time due to insufficient information. To obtain this information, it would be necessary to consult more detailed public documents such as official Cabinet Office announcements, personnel transfer information, or the organizational chart of the office.

### Verification
The establishment of the 'Tax Special Measures and Subsidies Review Office' within the Cabinet Office's Administrative Reform and Efficiency Promotion Secretariat on November 25, Reiwa 7, is confirmed by the Cabinet Office's official website (Source 7) and multiple news reports (Sources 3, 4, 5). Its purpose is to promote the optimization of tax special measures and subsidies (Source 7). Regarding the office's scale, reports indicate the establishment of a '30-person office' (Source 6), and it has also been suggested that 'all staff members are working concurrently' (Source 8). However, none of the provided sources include a list explicitly stating the names of individual staff members belonging to this office, their specific concurrent positions, or their terms of service. The names of relevant ministers and vice-ministers are mentioned as attendees of meetings related to this initiative, but these do not constitute a direct 'staff list' for the office.

### Supplement
There also exists a ministerial position titled 'Minister in Charge of Reviewing Tax Special Measures and Subsidies,' but the provided Wikipedia article (Source 1) states that it 'lacks sufficient or any sources,' making it unreliable for determining if this minister also serves as staff for the 'Tax Special Measures and Subsidies Review Office,' its establishment period, or the specific names of past ministers.
