The policy was enacted by the Tokugawa shogunate under Tokugawa Iemitsu through a number of edicts and policies from 1633–39, and ended after 1853 when the American Black Ships commanded by Matthew Perry forced the opening of Japan to American (and, by extension, Western) trade through a series of unequal treaties.

Boxing in Japan: The history of boxing in Japan began in 1854 when Matthew Perry landed at Shimoda, Shizuoka soon after the Convention of Kanagawa.  At that time, American sailors often engaged in sparring matches on board their ships, with their fists wrapped in thin leather.  It was the first example of boxing conveyed to Japan.  In addition, an ōzeki-ranked sumo wrestler named Tsunekichi Koyanagi (小柳 常吉 ) was summoned by the Shogunate, and ordered to fight a boxer and a wrestler from the United States.  The three fought matches, using different martial arts' styles, before Perry and other spectators.  Koyanagi reportedly won.

The bay is surrounded by the municipalities of Uruma, Kitanakagusuku, Nakagusuku, Nishihara, Yonabaru, Nanjō, all in Okinawa Prefecture.

Jeddo, Japan: Jeddo and Yedo or Yeddo are anglicisations referring to the town and port of Edo, Japan and the adjacent large bay, and generally to the ruling shogunate of Japan during the 1850s and 1860s, which was based in Edo.

The names Jeddo and Yedo became commonly used by English-speaking people in the mid-1800s, following the expedition of Commodore Matthew Perry, which resulted in the opening of Japan to trade.  Neither name is in common use today, as a name of reference for Edo, or the bay, or the Tokugawa shogunate associated with Edo.
