Thanks @alia and @ficelle!
"KENJI'S Room" (Talk show of Kenji and yuzu) preview video of 5minutes is uploaded!
KENJI'S Room Preview video
Edit: My gist about the KENJI'S Room Preview video is as follows;
(Now, we are looking forward to Kenji’s Room in September!:

)
(1)They talked about “figure skate” and “choreography” deeply or professionally as a top skater and choreographer, respectively. The content of the talk sounds interesting.
(2)Talk show often enables long and relaxed talk unlike interviews. Yuzu emphasized the benefit of it. Yuzu talked about his daily life and hobbies. He said he could show another side of him fully in the relaxed talk.
(3)Yuzu mentioned their regional difference about temper (In a nutshell, Tohoku region people are Serious (ex.yuzu); Kansai region people are merry or comical (ex.Kenji, Nobu), which leads to the funny contrast and effect. Other than that, there must be a good chemistry between them, like that of Nobu and yuzu or of Tatuki and yuzu.
(4)Kenji just admired yuzu’s intensive practice. About the episode of their choreography work, yuzu puts on earphone and moves all the time, following the movement. Yuzu doesn’t take a break during the choreography work.
(5)Surprisingly, yuzu said he’d imaged just all the things in the case of Olympic gold medal, since he was a small child. Now, he becomes Olympic Gold Medalist. We can hear his current state of mind considering that stuff, his childhood thought.

The preview can only be watched after you register for
free login to Jsport .
Here is the preview translation. Sounds like Yuzu talked a lot in the Room
Questions:
(1) Do I understand correctly that there will be 5 episodes of Yuzu's interview? And these are the broadcast dates
Sept 1, Sept 8, Sept 15, Sept 22 and Sept 29?
(2) Anyone knows how do we can watch the interview? Will it be broadcasted on TV or via online at Jsport?
(1) = You understand correctly^^ Each episode will last 30 minutes (from 10 pm to 10:30pm)
(2) = It will be broadcasted on JSport 4 (private channel with access through the cable in Japan). Otherwise it seems there is a plateforme where the program will be distribued on vod (not free of course). But you can't souscribe if you don't live in Japan. I tried and I got the "this service is not available in your area" message. :/
But I suppose some kind fans will upload the video for us on youtube/dailymotion

It should be fine ^^
