Their SWF flash player has the following references:
rtmp://fms.tc.fujitv.co.jp/fujimic/
rtmpt://fms.tc.fujitv.co.jp/fujimic/

So it must be an RTMP stream. Flash .FLV RTMP streaming videos can be recorded with Replay Media Catcher, FLV Recorder.

You may also try to find rtmp:// URLs with URL Snooper, but you should add "flv;rtmp" to the "Also search for" edit box.
