This episode is the first back at the usual NHK Hall stage for the episode filming after the more subdued episodes of the previous month. The March Tohoku earthquake/tsunami is of course still a fresh subject and the show is affected by it with really pushing an emphasis on being uplifting. This is also the first episode that uses what will be the usual set up for hosts with three members of the group being the hosts.
So the show is returning to form even though it is a different one simply because it has begun a new season so all the changes that come with that are now able to be implemented. But this is now the era of Hey! Say! JUMP hosting and there are three debuts coming up in quick succession of each other, starting with Kisumai's.
Watching this does remind me that I have fallen behind in general with following the Juniors. I think I may need to do some catching up with that, though honestly I just have not been interested in them as a whole for a while outside of a few that I have been a fan of for years. So I am curious if my interest will be renewed or not, though I do know I am getting closer to when SC is more about recently debuted groups than Juniors so who knows.
