I attend the insanely early (5:30 am) event of the 29th annual Toshima-ku radio taiso taikai. Which in essence is an event for the whole community to get together and do the nationally broadcast radio morning exercises. Its an interesting and very "Japanese" activity in my opinion. On a normal day, you will find people gathered in small local parks doing this. This larger event is held once a year. I couldn’t really catch any clear purpose as to why. For more info about Radio Taiso check out this wikipedia link. en.wikipedia.org Apologies if its not my most thrilling post to date. I can only be so entertaining at 5:30 am. PS Some added info after reading the comments. No daylight savings time in Japan as a result in summer it gets bright really really early. And vice versa in winter. Also yes, I am fine. The earthquake recently was no problem. Had a few seconds of "Oh Crap!" But no problem at all.
