A console that is selling 6K-7K weekly sales in its fifth year on the market obviously won't have good legs, it has already proven to have bad legs. Switch 1 hasn't even reached those weekly sales in Japan after being on the market for a longer time plus having been replaced by a new console. So no, PS5 won't rack up much better sales figures than it has today, it will continue to crawl in sub 10K weekly sales with a few bumps here and there during holidays and promotions.
I guess the main interesting factor regarding PS5 in Japan will be to follow its competition with Switch 1 sales during the rest of 2025 and 2026 (As long as Switch 1 units are still being produced really).
