日本足协主席：日本没8万人球场，或联合申办2046世界杯（日本足协主席称日本暂无8万人容量球场，或与他国联合申办2046年世界杯）

Considering news response

The user shared a Chinese news headline about Japan's potential to co-host the 2046 World Cup. They didn’t ask a specific question, so I’m thinking they might want a summary, analysis, or context. Since I can't browse the internet, I should clarify by asking if they want a summary or more details. It would also be good to provide context about FIFA's requirements for stadium capacities and recent information on upcoming World Cups.Assessing World Cup requirements

For the 2026 World Cup, I see that stadium requirements mandate 60,000 seats for semis and 80,000 for the opening and final matches. Without an 80,000-seat stadium, co-hosting would be necessary. Japan's largest stadium is about 72,000, which isn't sufficient. They might explore temporary expansions, but that's complex. Co-hosting options could include South Korea, China, or Australia. I should clarify with the user if they want a news summary or more details on these implications.Preparing World Cup response

I need to avoid heavy formatting in my response, so I'll aim for 4-6 bullet points. I want to provide a quick summary covering what was said, why it matters regarding FIFA requirements, the current stadium situation in Japan, potential co-host partners, timelines, bidding cycles, and any obstacles or next steps.

I should also ask how the user would like me to proceed—like if they want deeper analysis or information on stadium capacities. Possible co-host partners could include Korea, Australia, and China, along with ASEAN countries like Indonesia, Thailand, and Malaysia.Validating FIFA requirements

I need to confirm the FIFA 2026 requirements: the final match stadium must have at least 80,000 seats, and the opening match likely requires the same, while semifinals need 60,000, and group/round of 32 matches require 40,000. This is accurate.

I should mention that the 2046 cycle isn't open yet and refer to FIFA's rotation policy. After a confederation hosts, it can't host again for two cycles. With this context, the JFA president is considering co-hosting for 2046, considering partners like Australia, China, and South Korea.Exploring co-hosting possibilities

I’m considering that 2034 will be hosted by Saudi Arabia, but co-hosting 2046 with Australia could be feasible if it's between the AFC and OFC, since they are separate confederations. It’s not impossible, especially given the unique hosting setups for the 2026 and 2030 Cups.

I'll present these facts in a bullet summary and then ask the user what they would prefer next: a deeper breakdown or a translated article. Since the user wrote in Chinese, I should respond in simplified Chinese.
