台場有段有趣的歷史 —— 截取自維基百科。
The name Odaiba comes from a series of six island fortresses constructed in 1853 by Egawa Hidetatsu for the Tokugawa shogunate in order to protect Edo from attack by sea, the primary threat being Commodore Matthew Perry's Black Ships which had arrived in the same year.
Daiba in Japanese refers to the cannon batteries placed on the islands. In 1928, the Dai-San Daiba (第三台場) or "No. 3 Battery" was refurbished and opened to the public as the Metropolitan Daiba Park, which remains open to this day.
Dai-Roku Daiba (第六台場) or "No. 6 Battery", one of the original Edo-era battery islands, as viewed from the Rainbow Bridge. The developed area of Odaiba is in the background.
One of the cannons of Odaiba, now at the Yasukuni Shrine. 80-pound bronze, bore: 250mm, length: 3830mm. From the originally planned 11 batteries, only five were ever finished. The modern island of Odaiba began to take shape when the Port of Tokyo opened in 1941.
Until the mid 1960s all except two batteries were either removed for unhindered passage of ships or incorporated into the Shinagawa port facilities and Tennozu island. In 1979 the then called landfill no. 13 (now Minato-ku Daiba, Shinagawa-ku Higashi-Yashio and Kōtō-ku Aomi districts), was finished directly connecting with the old "No. 3 Battery". "No. 6 Battery" was left to nature (landing prohibited).
