Yahoo Japan & Yahoo have just launched Yahoo Site Explorer for the Japanese market, which Yahoo search & services dominate.
Using Yahoo Japan Site Explorer, Japanese webmasters or companies targeting the Japanese market can track their URLs and incoming links and also upload sitemap files into Yahoo.
Unlike the US version of Site Explorer, Yahoo Japan Site Explorer is more geared towards the independently managed Yahoo Japan market. According to the Yahoo Japan Search Blog, the Y! Japan Site Explorer includes tracking of Bookmarks, listings in Yahoo Japan Blog Search, page views and mobile search information is coming soon.
Yahoo also recently launched Site Explorer for the UK market, and is redirecting Yahoo.com to the domestic URLs of the International user, so it seems that the company is making a big push to win over webmasters in different regions.
