Yahoo Japan has nothing to do with the American Yahoo tho... It looks beautiful btw: https://www.yahoo.co.jp/ - still using the old look.
"In 2017, Verizon Communications purchased the core internet business of America-based Yahoo!, and merged them into Oath, Inc. Yahoo! Japan was not affected. It continued as a joint venture between Softbank and what remained of Yahoo! Inc., renamed Altaba."
Notably, prior to its acquisition Yahoo! (America) had a 35% stake in Yahoo! Japan along with 24% of Alibaba. Even while Yahoo! was independent and turning a profit, it was valued as an albatross dragging down Yahoo! Japan's prospects to the tune of about negative $4 billion.
People were suggesting that a holding company should be broken out to manage all three entities without doing any business of its own, so that Yahoo's terrible prospects couldn't cut into the value of the other two. (Since an independent business can't be worse than worthless to shareholders, it would have immediately switched to a positive valuation.) Instead, the market skipped a step, divesting the functional businesses to enable a positive-value acquisition of the remains.
What's fascinating is that Yahoo! Japan does something very similar to Yahoo! America, but one of the two profitable businesses was valuable while the other was understood to be doomed.
As for the rest of the world, I don't see the point of Yahoo anymore.
