Last year we visited the socalled Yamakasa festival in Fukuoka, Japan, from wikipedia:
Yamakasa – held for two weeks each July, is Fukuoka’s oldest festival with a history of over 700 years. Teams of men (no women, except small girls, are allowed), representing different districts in the city, race against the clock around a set course carrying on their shoulders floats weighing several thousand pounds. Participants all wear shimekomi (called fundoshi in other parts of Japan), which are traditional loincloths. Each day of the two-week festival period is marked by special events and practice runs, culminating in the official race that takes place the last morning before dawn. Tens of thousands line the streets to cheer on the teams. During the festival period, men can be seen walking around many parts Fukuoka in long happi coats bearing the distinctive mark of their team affiliation and traditional geta sandals. The costumes are worn with pride and are considered appropriate wear for even formal occasions, such as weddings and cocktail parties, during the festival period.
Yamacasa is quite a dizzying event that is if you are amidst it is hard to figure out what is going to happen, there is a lot of press and and a lot, lot of people at the festival. here some images:
