Pudong and it's skyscrapers including Shanghai Tower
These are the tallest buildings in China. They are located in Pudong, Shanghai across from the Bund. Shanghai Tower is the tallest at 128 floors followed by the Shanghai World Financial Center and the Jin Mao Tower. The colorful building to the left is Pearl Tower which was the tallest building in China until 2007.
Taipei 101 lies in Taipei, Taiwan. It was the tallest building in the world (2004-2010) until the Burj in Dubai was completed and opened to the public in 2010. This structure towers over the rest of the city and it is strong enough to handle Taiwan's earthquakes and typhoons. The elevator can travel as fast as 41 feet a second. There are great views of the city and mountains surrounding Taipei from the top.
This building towers over Koahsiung, Taiwan. I remember when I would drive my scooter from my home in Tainan to my work in Alian in Koahsiung county. You could see this building towering off in the distance about 25 km away. From the top there's a gallery with nice music and you get a great view of the city including Monkey Mountain.

This is the tallest structure in Japan. It is also the world's tallest broadcasting tower.
