Considering user query

The user provided a statement in Chinese about Japan's football association president discussing stadium capacity and a potential joint bid for the 2046 World Cup. It seems like they might want a summary or some context regarding this news. Since there's no explicit question, I should consider asking for clarification or offering a brief overview. I’ll keep in mind my knowledge cutoff from 2024, but the date implies this news could be from after that.Providing context on stadium capacity

I want to avoid making up details, so it's essential to provide general context about FIFA's stadium requirements for the World Cup. The opening match and final need around 80,000 capacity, while semifinals require 60,000 and earlier rounds need 40,000. Since Japan lacks an 80,000-seat stadium, they can’t host the final alone. They might consider a joint bid with countries that have such stadiums. Interestingly, Japan's largest stadium, the New National Stadium in Tokyo, has around 68,000 seats, confirming the JFA president's statement.Clarifying JFA leadership and context

Kozo Tashima served as the JFA president from 2016 until 2024, and I think he had COVID early in 2020. In March 2024, Tsuneyasu Miyamoto, a former player, was elected JFA president. I recall something about him being a general secretary or technical director too. Hajime Moriyasu is the head coach, and Yasuharu Sorimachi was vice president. The user might be curious about Japan potentially co-hosting the World Cup with South Korea or ASEAN, considering past tournaments. The upcoming World Cups in 2030 and 2034 are set, so the next one for Japan could be in 2038 or later.Exploring World Cup hosting options

FIFA chooses hosts every two cycles, with 2034 confirmed for AFC, which likely means 2038 won't be in Asia. They’ve moved away from strict rotation but still avoid consecutive confederations. After 2034, it could be CONMEBOL, CONCACAF, UEFA, or CAF for 2038. Japan might aim for 2042 or 2046, especially if AFC gets another turn in 2046. The user’s reference to co-hosting makes sense; Japan could partner with South Korea or China, depending on stadium capacities and requirements.Exploring co-hosting options

Japan can consider several potential co-hosts for the World Cup. Australia has large stadiums like the MCG and Stadium Australia, while China has the Bird's Nest. Malaysia's Bukit Jalil Stadium meets the 80,000 requirement, and Qatar's Lusail could be a future partner. Japan could also think about expanding existing stadiums or building new ones. The FIFA requirement for the final is crucial, and we should clarify Japan's current stadium capacities and feasible partnerships. I'd like to know if the user prefers deeper analysis, scenarios, or a brief summary.
