Yahoo Japan to buy back $2bn in shares from former US partner [asia.nikkei.com]
Yahoo Japan is buying back around 221 billion yen ($2 billion) worth of shares from the former U.S. Yahoo -- now known as Altaba -- in a multi-step process that will also tighten its relationship with the mobile unit of top shareholder SoftBank Group.

The Yahoo name in Japan still has a lot of street cred. They didn't suffer from the poor performance of Yahoo in the US as they were related in name only for the most part. Under SoftBank, Yahoo is also a proper consumer ISP, and they still run a number of seemingly profitable portal services. Long ago they outsourced search to Google, but there is still a large portion of the Japanese populace who equate Yahoo with the internet, although Google has made significant inroads.
