A joint survey conducted by Asahi Shimbun and the University of Tokyo found that 93% of the elected representatives from the recent House of Representatives election support constitutional amendments, a significant increase from 67% in the previous election held in 2024. Among the proposed amendments, the inclusion of the Self-Defense Forces in the constitution, as advocated by the ruling Liberal Democratic Party (LDP), was favored by 80% of those surveyed. This marks a notable shift in sentiment as this is the first time since the survey began in 2003 that more than 90% of elected officials support the amendment path.

The survey highlights a drastic shift in opinions, with support for the amendments coming primarily from the ruling LDP which has achieved a supermajority in the House of Representatives. The coalition parties, including Nippon Ishin no Kai and several opposition parties, are increasingly supportive of the amendments, creating a dominant outlook favoring changes to the constitution. The implications of these findings suggest a strong possibility of constitutional amendments being proposed in the Diet, which requires at least a two-thirds majority from both chambers to proceed.

Furthermore, the survey posed the question of whether there was a need to change the current constitution. The results showed that 93% of respondents, including those who somewhat agreed, favored amendments, a stark decrease from the 23% opposition observed in the previous election. Only 3% identified as opposed to amendments, with 4% remaining neutral, indicating a significant shift towards approval for constitutional reform in Japan.
