district director
税務署長
The head of a tax office (税務署), the local office of the National Tax Agency that deals with taxpayers in its district (Act for Establishment of the Ministry of Finance, Article 24). It is the office a person usually deals with: an income tax return is filed with a district director (Income Tax Act, Article 120, paragraph (1)), and reassessments, determinations and the collection of national tax are done by the district director for the taxpayer's current place for tax payment (Act on General Rules for National Taxes, Articles 30 and 43). A person who objects to what a district director has decided can ask that director to look at it again (再調査の請求) or go straight to the National Tax Tribunal (Article 75, paragraph (1), item (i)) — unless the notice of the decision says officials of a Regional Taxation Bureau or of the National Tax Agency investigated, in which case it counts as the regional commissioner's decision, with the same choice, or as the Commissioner of the National Tax Agency's, which can only be challenged by a request for review to the Commissioner (Article 75, paragraph (2)).
