According to Nikkei, messaging app Line and Yahoo Japan are about to merge and form a single tech company. Despite the name, Yahoo Japan is currently 100% owned by Z Holdings, a company that is controlled by Japanese telecom company SoftBank (Yahoo Japan isn’t related with TechCrunch’s parent company Verizon Media). Line Corporation is owned by Naver Corporation, a South Korean internet giant.

The two companies are still discussing terms of the deal according to Nikkei. But you could imagine Z Holdings becoming a a 50-50 joint venture between SoftBank and Naver, with Z Holdings owning both Yahoo Japan and Line.
