I apologize for the oversight. While I don't have access to real-time data or specific polls at the moment, I can provide some general information based on past surveys and studies.
Historically, public opinion polls in Japan have consistently shown high levels of support for the Emperor system. For example, a survey conducted by NHK, Japan's national public broadcaster, in 2019 found that around 85% of respondents expressed positive views towards the Imperial family. Similar polls conducted by other organizations have also indicated strong support for the Emperor system among the Japanese population.
Additionally, events such as the abdication of Emperor Akihito in 2019 and the enthronement of Emperor Naruhito have attracted widespread public attention and expressions of support for the Imperial family.
While specific numbers may vary depending on the timing and methodology of the surveys, the overall trend suggests that the Emperor system enjoys significant popularity and respect among the Japanese people.
If you are interested in more recent and specific data, I recommend checking official sources such as government surveys, polling organizations, or news outlets that regularly report on public opinion in Japan.
