In June 2023 the Diet passed immigration-law revisions Kishida’s government backed, including deportation of some repeat asylum applicants.
Context
MOJ implements. He did not sit as an immigration judge. A revision is still a dated restrictiveness instrument.
Ageing/childcare is a neighbouring demographic row that cuts the other way on labour supply.
Japan’s prime minister is appointed by the Emperor after Diet designation and chairs the cabinet. He does not write US NDAA lines, IAEA operating licences, a Korean statute, or LDP faction ledgers as if they were gazettes. A Hiroshima G7 photo is not a treaty. A resignation is not a unique CPI coefficient. Treated-water discharge is not a finding that every fishery was thereby safe. He is not prime minister in 2026: Ishiba then Takaichi succeeded him. A state funeral is not a Diet budget by itself. A Kyiv visit is not a HIMARS transfer. A My Number error is not a completed theft.
Why it matters
The path is migration-policy restrictiveness: a completed deportation-and-asylum-clock revision raises restrictiveness for some applicants.

What the sources establish
Ministry of Justice Japan carries the official instrument or communique. Reuters records the same dated act independently.
Established: a June 2023 immigration-law revision under his government, independently reported.
Not established: that every applicant was abusive, or a unique later labour-shortage coefficient.
The Diet passed. MOJ implements. Applicants appeal.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Diet revises immigration law including deportation and asylum-clock rules, not a later speech about Diet revises immigration law including deportation and asylum-clock rules.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to His cabinet backed. The Diet passed. MOJ implements. Applicants appeal. That limit is the alternative to treating office-holding as authorship of every later series.
