For mobile network in Japan, it is considered that SoftBank's acquiring WILLCOM (PHS, simple cellular phone operator) and eAccess (also cellular operator) were a smart move. They gained already assigned frequency bands for them. Govt should had stopped it for fairness. Acquiring LINE (messaging service dominant in Japan, and also in some asia countries) looks good move but it is still not monetized well. Investing Yahoo! looks succeeded, perhaps? I don't know when they sold. Investing WeWork is really terrible to see.
