Bonus photosA meteor from the Perseid shower is seen in the sky above a lone pine tree in the Iwate Prefecture city of Rikuzentakata at 3:17 a.m. on Aug. 13, 2011. The pine tree miraculously survived the tsunami that devastated the city five months earlier. The Perseid meteor shower, which is visible around the Obon period each year, reached its peak on Aug. 13. Viewing conditions were poor this year due to a full moon on Aug. 14, but several meteors could be seen per hour in the sky above the tree.

The ribbons are part of a project by artist Akira Hosokawa to hang 1,000 ribbons in paddy fields of the tsunami-devastated city and "bring color to a world of gray." Written on the ribbons are messages of hope from locals. The project will run through Aug. 17, with a candlelight vigil scheduled to take place on Aug. 15.

The display was part of a fireworks event titled "Light Up Nippon" that was staged in 10 cities in Iwate, Miyagi and Fukushima prefectures, which were hit hardest by the disaster. Some 20,000 fireworks were used in the event, which was planned partly by young people in Tokyo.
