Last fall I had solicited the recommendations of fellow RS fans for Japan tour operators. Specifically, operators that ran tours in the RS style. The thread is now closed:

I thought I'd reference that old thread here because I finally booked with Inside Japan Tours, which was one of the recommendations offered up. This will be our first time going to Japan and we're quite excited about that. The tour is 11 days long so we're taking an extra 4 days to explore Tokyo on our own after the tour ends. If any one else has had experiences with this company, I'd love to hear about it. Better yet, if you're going on this same tour (Nov. 19th departure of the "J-Pop & Go" tour), I'd love to know!
