Yokohama Arena (横浜アリーナ, Yokohama Arīna^?) is an indoor arena located in Yokohama, Japan. The capacity of the arena is 17,000 and was opened in 1989. The arena was modeled after US sports venue Madison Square Garden in New York City. It is a five minute walk from the closest subway station, Shin-Yokohama Station on the JR/Yokohama Municipal Subway.

As one of the largest concert venues in the Kantō region, it is a frequent location for artists to end their tours. The spacious stage allows for more complex set design and lighting, but the reasonable size makes it easier to sell out than the Tokyo Dome.

After the 2011 Tōhoku earthquake and resulting tsunami, Yokohama played host as an emergency shelter for those affected by the earthquake and tsunami. Citizens were allowed the stay the night, and were offered blankets and other amenities. Hideharu Terada, a Yokohama Arena official stated "There has never been a big earthquake like this. [...] People are trickling in. They are all calm."

Yokohama (横浜市, Yokohama-shi^?, "Side Shore") ( listen (help·info)) is the capital city of Kanagawa Prefecture and the second largest city in Japan by population after Tokyo and most populous municipality of Japan. It lies on Tokyo Bay, south of Tokyo, in the Kantō region of the main island of Honshu. It is a major commercial hub of the Greater Tokyo Area.

Yokohama's population of 3.7 million makes it Japan's largest incorporated city.

Yokohama developed rapidly as Japan's prominent port city following the end of Japan's relative isolation in the mid-19th century, and is today one of its major ports along with Kobe, Osaka, Nagoya, Hakata, Tokyo, and Chiba.

Yokohama was a small fishing village up to the end of the feudal Edo period, when Japan held a policy of national seclusion, having little contact with foreigners. A major turning point in Japanese history happened in 1853–54, when Commodore Matthew Perry arrived just south of Yokohama with a fleet of American warships, demanding that Japan open several ports for commerce, and the Tokugawa shogunate agreed by signing the Treaty of Peace and Amity.

Hideaki Tokunaga (德永 英明, Tokunaga Hideaki^?, born February 27, 1961 in Yanagawa, Fukuoka Prefecture) is a Japanese pop singer-songwriter and actor.

Although Tokunaga failed to pass the test of Star Tanjō! in 1982, he debuted as a recording singer in 1986. After he released hit songs such as "Yume o Shinjite" (the first ending theme of the anime series Dragon Warrior: Legend of the Hero Abel) and "Kowarekake no Radio" in 1990, his single "Wednesday Moon" reached No. 1 on Oricon weekly charts in 1991. He was also known for Vocalist album series, comprising his covers of female songs. Vocalist, Vocalist 2, Vocalist 3 and Vocalist 4 were released in 2005, 2006, 2007 and 2010 respectively.

Tokunaga is the first male artist to have at least one album to reach the number-one position on the Japanese Oricon weekly charts for four decades (1980s, 1990s, 2000s and 2010s).

Tokunaga also composed other singers' songs such as KinKi Kids' "Eien Ni" (from their 2007 album Phi).

Tokunaga took part in the Japanese television program Star Tanjō! in 1982. The program produced many Japanese stars such as Momoe Yamaguchi, Pink Lady and Akina Nakamori. However, Akiko Matsumoto passed the test at that time, while Tokunaga and Minako Honda were rejected.
