Tokyo Sky Tree is on target to be the tallest structure in Japan upon completion in the spring of 2012, reported constructiondigital. Located in the Narihirabashi/Oshiage part of the Sumida Ward of Tokyo, the Tokyo Sky Tree broadcasting tower will soar nearly 634 meters into the sky, making it one of the tallest in the world and an icon of Japan. Designed by Nikken Sekkei, the tower, which resembles a large tree, will serve as a hub for the country's digital terrestrial broadcasting network. Additionally, the structure features two observation decks and is designed to withstand Japan's frequent earthquakes as well as strong winds. Though many may see this as Japan's way of getting in the race for the world's tallest structure, the height of the Tokyo Sky Tree serves an important function-it improves the towers ability to send the broadcasting signals over the tall skyscrapers of Tokyo. The base of the tower resembles a tripod. The three 'legs' anchor the structure to the ground. As it rises, the structure begins to curve around a central tube into the sky. Observatory levels at 350 meters and 450 meters allow visitors to have panoramic views of the urban landscape. The lower level will feature restaurants and retail opportunities. Japan isn't a stranger to earthquakes and strong storms. As a result, architects must design structures with disaster prevention features to withstand movement from above and below. Taking inspiration from the traditional Japanese pagoda, the tower relies on a central column for stability. According to the architects, "this system counters swaying set in motion by earthquake tremors and strong winds, ensuring a safe and reliable structure." The Obayashi Corporation is serving as the general contractor on the Tokyo Sky Tree project.

Japanese construction corporation Obayashi Corp., is planning to complete the construction of the world's tallest tower - Tokyo Sky Tree in spring 2012. A tower with a height of 634m previously was planned to be finished at the end of 2011. By turnover 2009, Obayashi Corp. is the world's 22 biggest construction company. The long uppermost section of tower is the "antenna tower" for digital-terrestrial broadcasts. Below of "antenna tower" it will be located the world's highest observatory deck with height of 450m. The developer of the tower is Tobu Tower Sky Tree Co., Ltd., architecture-Nikken Sekkei Ltd. Tokyo Sky Tree will equipped by 6 Toshiba elevators, four out of which are 40person elevators with a maximum speed of 600m/min, which are the fastest large capacity elevators in Japan. The new tower's foundation developed by Obayashi will be subjected to strong uplift and compressive forces from winds, earthquakes, and other factors. Note that record for the tallest building in the world still belongs to Burj Khalifa in Dubai with height 828m!

One of Tokyo's most famous buildings the Nakagin Capsule Tower threatened with demolition. Designed by Kisho Kurokawa in 1972, it caught the world's attention with its minuscule living spaces for the country's single office workers. The striking tower, in Tokyo's Shimbashi district, even appeared as a Japanese love hotel in the 2013 blockbuster "The Wolverine" starring Hugh Jackman. But over the years, much of the once-modern building has fallen into disrepair. Around half of the 140 units are used as offices, art studios, and second homes, but just 20 are lived in full-time. Each of the 140 units in the tower contains a bed, a fold-out desk and a tiny bathroom; all squeezed in just 10 square meters. Rent for a capsule is around 60,000 yen (US $539) per month. The rooms feature a large round window and retro features such as clocks and sound systems, giving them the appearance of being suspended in a 1970s vision of the future. The building's dilapidated state does not make for an easy life. The capsules' asbestos insulation is deteriorating, so winters are cold, and summers can get very hot. Corroding pipes, water damage, and an uncertain future mean half the capsules have been left to rot by their owners, who would rather see the tower demolished and reap the profits of a brand new apartment building. The individual capsules were originally designed to be removed and replaced every 25 years, except that failed to happen. This isn't the first time that the building has faced the threat of demolition. Back in 2007, CTBUH reported similar findings, where the building's management actually approved plans to raze the tower. These plans eventually fell through and the building still stands today. While some owners are keen to restore the building, others feel demolition is the best route. Eighty percent of them need to agree on any changes, before a decision is made. Meanwhile, a crowd-funding project hopes to safeguard the future of the 13-story tower - that some see as a monument to Japanese architectural history. The campaign, known as the "Save The Nakagin Capsule Tower Campaign" aims to collect donations from people all over the world who love this capsule tower and use that money to buy the capsules one by one. But Japan, like many countries in Asia, often prefers the new to the old. Christian Dimmer, Professor of Urbanism at Tokyo University, told AFP news agency: "It is hard to raise public awareness about the preservation of historic buildings in Japan, where buildings are usually torn down and replaced after 30 years."
