Sure, this is actually a more obscure source that wasn't widely reported on Japanese media but was written by a Japanese author on a Singaporean website.Could you share the source for this "40% of Japanese youth are pro China"? This is the first time I hear of it. I always thought the vast majority of Japanese are anti China.
In the Public Opinion Survey on Diplomacy by the Cabinet Office of Japan conducted at the end of 2021, just over 10% of respondents in their 60s and 70s — those with the harshest attitudes toward China — answered that they felt “close, friendly or familiar” with China. On the other end of the spectrum, over 40% of respondents aged 18 to 29 gave the same response. This indicates that the younger generations are more likely to have better perceptions of China.
