The movie is available at doramax265 and has not been subbed to my knowledge. I don't think its on avistaz. Highly recommended movie.
They started at the south exit of Nakano station.
And moved south.
The yatais are a lot smaller than the one from A Living Promise but it brought great memories from the movie.
Afterwards there was a taiko performance at the north exit. Really awesome.
The taxi driver guy in the middle turns out to be buchou / boss of the organisation and he gave a short speech. It was surreal because of watching so many doramas and movies about shopping area organisations and everyone was shouting buchou!!!! there was a JR! chant which I assume is his nickname.
All three yatais got together for a dance/shout off...
And then headed north up Nakano broadway. I miss Nakano. The good thing about Nakano is that its within walking distance to Koenji which has interesting nightlife as well. :)
