Yasukuni Shrine's annual Mitama Matsuri is one of Tokyo's largest Obon festivals. First held in 1947, the festival is best known for its 30,000 lanterns – 10,000 larger lanterns light the approach to the shrine, while 20,000 smaller ones are set up at the inner shrine grounds. This year, the lanterns will be illuminated daily from 6pm until July 16. You can also look forward to dance and taiko drum performances, portable shrine processions and more. Note that food stalls have been cancelled this year.
The event takes place daily from 6pm to 9.30pm.
