If there is one thing I have learned from watching Japanese anime, TV shows or movies, it is that the Japanese culture really LOVES roll calls and transformation sequences (actually, I think Asian cultures in general love roll calls). There is something about taking turns and calling out your name while doing some kind of sequence plus pose that makes my inner five-year-old go nuts. Of course, it is apparently disrespectful to disturb a roll call sequence in progress, but this is a different matter altogether.
Below is a random example using footage from the Super Sentai series (commonly known as Power Rangers to westerners). There are some stylish and cool elements about something that one could chalk up as a very Japanese thing to do.
Dat roll call.
