Feedburner.jp - the Japanese version of Feedburner

Judging from the logo, it should be a sub-service of Feedburner opened in Japan. I can't figure out why Feedburner needs to set up a sub-website specifically. I tried other related national domain names and found that there seems to be only this Japanese sub-domain currently. After trying it, I feel it's no different from the familiar Feedburner before. I don't know what Feedburner is thinking.
