Yoyogi National Stadium

HarajukuYoyogi National Stadium (????????, Kokuritsu Yoyogi Kyogi-jo?) in Shibuya, Tokyo, is an arena in Yoyogi Park, Tokyo, Japan which is famous for its suspension roof design. It was designed by Kenzo Tange, Japan's foremost postwar architect.

It was built between 1961 and 1964 to house swimming and diving events in the 1964 Summer Olympics. This stadium located across the Inokashira Avenue from the Yoyogi Park. The Stadium is one of Tokyo's most impressive landmarks. National Yoyogi Stadium is also in Harajuku area. Located in Yoyogi Park which is also where Meiji Shrine located, no wonder National Yoyogi Stadium is one of most attended place in Tokyo.

The design inspired Frei Otto's arena designs for the 1972 Summer Olympics in Munich. its awesome and daring shell-like steel-suspension roofing has earned it a spot in the Japanese Ministry of Construction's Top 100 Public Structures of Japan. The stadium seats 8,000 and is used for concerts, mostly rock, as well as sporting events.The arena holds 10,500 people. A CFD evaluation of the stadium interior was recently performed by the Shimizu Corporation to better understand the quality of the air-conditioning system for both modes of stadium operation.

Nowadays, this Stadium also being used for ice skating and volleyball competitions, basketball competitions, concerts (it's a nice place to concert) and various other events. In October 1997, the NHL opened its season at the arena with the Vancouver Canucks taking on the Anaheim Mighty Ducks in two matches. The following season the San Jose Sharks played the Calgary Flames in two games also to open the 1998-99 NHL season.

National Yoyogi Stadium, a holy place for athletes in Japan. The design of the stadium applied the same technique as a suspension bridge and the 126-meter long and 120-meter wide roof hanged from one or two main posts is providing a large open space. With its unique and stunning design. It has employed innovative suspended roof construction utilizing high tension cables, and we are proud of their unique shapes. The premises feature the 1st gymnasium, which looks like a tent supported by two columns; the 2nd gymnasium, which looks like a dragon spiraling towards the sky; and other sports facilities. The stadium was used for international competition in swimming, volleyball, basketball, tennis, and ice skating and has brought up and sent many athletes into the world, becoming a place for people who love sports.

Two of the stadia, built for the Olympics, remain the area's most famous architectural features. The main building of Tange Kenzo's Yoyogi National Stadium is a dead ringer for Noah's ark, and its steel suspension roof was a structural engineering marvel at the time. Inside are a swimming pool and skating rink (Mon-Sat noon-8pm, Sun 10am-6pm; ¥900). The smaller stadium, used for basketball, is like the sharp end of a giant swirling seashell.

The damper mechanism from KYB protects the elegant suspended roofs of the gymnasiums from vibration due to strong winds and earthquakes. It supported the roofs and the history of the gymnasiums for more than 40 years. The damper mechanism is the root of the present vibration insulation system. In 2004, an overhaul of the system was conducted, and it was proved that 12 dampers removed from the building had maintained the designed performance after 40 years of service. The same technology is used in the large roofs of Fukuoka Dome and Oita Dome.
