Connecting Europe and Asia through an undersea tunnel
The Bosporus Strait divides Istanbul, Turkey’s largest city in two. One side is European while the other is Asian. The Bosporus Strait has a very strong current. Under the circumstances, our joint venture succeeded in difficult construction work that entailed the world’s first attempt at establishing an immersed tunnel in this location (60 m below the surface, the deepest in the world) and underwater jointing with a shield tunnel from both shores. The opening ceremony for the Railway Tunnel under the Bosporus Strait took place in February 2011. Tunnel facility construction and track laying as well as new construction of station buildings moved ahead. In October 2013, a magnificent opening ceremony for the subway took place, attended by the then-leaders Prime Minister Recep Tayyip Erdoğan and Prime Minister Shinzo Abe of Turkey and Japan, respectively. Other parties involved with the construction work were also present. The idea of a tunnel in this strait was called “the 150-year-old dream” of the Turkish people. Designs were drawn up back in 1860, during the days of the Ottoman Empire.

The birth of “The Okura Tokyo” about a half century after the opening of the Hotel Okura Tokyo
Kishichiro OKURA, who was the first son of Kihachiro OKURA often used to say, “the existence of top-notch hotels in the capital city is a ruler for measuring the culture of a given country.” Kishichiro resigned from all of his posts during the dismantling of Zaibatsu and the purge of public officials after World War II. When he was later reinstated at work, his final job was establishment of the Hotel Okura Tokyo. Based on the philosophy of “harmonization of Japanese tradition and modernity in a hotel,” the Hotel Okura Tokyo, which reflects time-honored Japan’s aesthetics, was opened in 1962. After the elapse of about a half century since its birth, based on the concept of “tradition and innovation,” the Hotel Okura Tokyo was remodeled into a 41-story high-rise building named the “Okura Prestige Tower,” comprising a hotel and offices, as well as the 17-story mid-rise building called the “Okura Heritage Wing.” We were involved in its design and construction, and the hotel was newly opened as “The Okura Tokyo” in September 2019.
Taisei Corporation and the former and new Japan National Stadiums
We handled the both the former and the new Japan National Stadiums, with their symbolic existences at Meiji Jingu Gaien. The former National Stadium was completed in 1958 with the capacity for about 50,000. At the time, it was the largest stadium in Asia. We completed it over a mere 14-month construction period. In 1963, we worked on an expansion of the number of seats to about 71,000, as well as traffic field conversion.
Moreover, we engaged in the design and construction of the current Japan National Stadium, which was completed in 2019. Based on the concept of “Mori no Stadium (Shrine Forest Stadium),” we completed this structure. It was built to stand in harmony with the forest surrounding Meiji Shrine and is open to the public. This is also a stadium unique to Japan that makes the country proud. In order to make it a reality, we included various concepts, technologies, and forms of ingenuity in the edifice, fully exerting all of our talents.
