Keita is a junior high science teacher in Iwate  岩手町. He sent me a photo of the Tokyo Sky Tower during a fireworks display. The Tokyo Sky Tower is a broadcasting and observation tower in Simide, a special ward in the Tokyo Metropolis. It became the tallest structure in Japan in 2010. In 2011, when it was completed at a height of 634 meters, it became the tallest tower in the world, and the second tallest structure in the world, after Burj Khalifa in Dubai, UAE.
