Japanese Supermarket Fish Tank

My last day at Kozoji ECC, I arrived at the station early to stop at the grocery store. Now, I never really go to this particular grocery store, and when I have, I just ran in and out because clock-in time was approaching. But today I had some time to wander, and boy was I kicking myself for not bringing my camera (sorry for the crappy quality by the way, this video was taken on my iphone)...in the corner of this supermarket there is a big fish tank with what appears to be sharks...for sale...in a grocery store...does that seem strangely awesome so anyone else, or it is just me?
