Iriya Asagao Matsuri (Morning Glory Festival) 2015

It's worth getting up early – as in crack-of-dawn early – for Japan's largest morning glory festival, held on July 6-8 every year in and around Iriya Kishimojin temple. Around 400,000 people head to the event each year, perusing the 120 flower booths and hundred-odd festival stalls on display, so prepare to battle some serious crowds.
