Although they have similar names and operate Web portals with a variety of services, Yahoo Japan Corp. is in many ways a very different company from Yahoo Inc.

Yahoo's profits have been falling because of competition from Google, Facebook and other popular sites. This prompted Yahoo to announce plans to cut 2,000 jobs — or 14 percent of its workforce — earlier this month.

At Yahoo Japan, which is not majority-owned by Yahoo, things are quite different. The company has seen both revenue and profit rise for the past five years as it dominates its domestic rivals.
