Anecdotally, I still use finance.yahoo.com because it's one of the best free sites out there for financial data. I also use fantasy.yahoo.com for some fantasy sports leagues I'm in.
For those unaware, Yahoo Japan is a separate company, with a somewhat parallel history.
It was a joint venture owned 50% by SoftBank. It went public as a separate company, and in 2018 took back all its ownership from the former Yahoo. In 2021, it merged with Line (also owned by SoftBank,) and bought the Japanese Trademark to Yahoo.
