Every law, and how to address a provision: https://japanlaw.org/llms.txt. The same laws as MCP tools (no sign-in): https://japanlaw.org/mcp. - Law: 出入国管理及び難民認定法 (Immigration Control and Refugee Recognition Act), 昭和二十六年政令第三百十九号 - English title "Immigration Control and Refugee Recognition Act": Ministry of Justice translation - Kind: Act — the distinction between 法律 (Act), 政令 (Cabinet Order), 省令 (Ministerial Order) and 条例 (local ordinance) decides who may issue it and what it may say. - Issued as a Cabinet Order and given the force of an Act, which is why its number says 政令: Some rules made during the Allied occupation were issued as Cabinet Orders, as orders implementing Japan's acceptance of the Potsdam Declaration, and an Act passed in 1952 gave them the force of an Act. They keep the Cabinet Order number they were issued under, which is why e-Gov lists the law as an Act while its number says 政令 (Cabinet Order). The Immigration Control and Refugee Recognition Act (出入国管理及び難民認定法) is one: it was promulgated in 1951 as the Immigration Control Order (出入国管理令), Cabinet Order No. 319 of 1951, has had the force of an Act under Article 4 of Act No. 126 of 1952, took its present title on 1 January 1982, and every amendment on e-Gov's record of it was made by an Act. - Provision: 第五十五条の六十一 (Article 55-61)（信書の内容による差止め等） — address `art-55-61` - Text in force since: 2026-10-01 - URL (the page that opens at this provision): https://japanlaw.org/ja/immigration-control-act/art-55-61 - Permanent URL (e-Gov law ID, never renamed): https://japanlaw.org/l/326CO0000000319/art-55-61 - Every provision below carries its address and both URLs on the line under it. - Japanese text: e-Gov 法令検索, Digital Agency (デジタル庁).
