Overview
- An April Mainichi smartphone poll of 1,868 adults found 37% support and 30% opposition to revising Japan’s constitution during Prime Minister Sanae Takaichi’s term, with 32% unsure.
- Support now exceeds opposition compared with the same point last year under Shigeru Ishiba, when 21% favored revision and 39% opposed it.
- Constitution Day events on Sunday showed active campaigns on both sides, with the conservative group Nippon Kaigi describing a sense that now is the time and peace groups staging public talks and rallies.
- A small youth survey by a civic group in Tokyo’s Shibuya reported about 60% against changing Article 9, based on 110 respondents, underscoring that views among young people can differ from national snapshots.
- Any amendment requires two‑thirds approval in both houses of the Diet and a national referendum, so the large pool of undecided voters could determine whether political momentum turns into a real bid to change the charter.
