In cultures where monogamy is mandated, bigamy is the act of entering into a marriage with one person while still married to another. A legal or de facto separation of the couple does not alter their marital status as married persons. In the case of a person in the process of divorcing his or her spouse, that person is taken to be married until such time as the divorce becomes final or absolute under the law of the relevant jurisdiction. Bigamy laws do not apply to couples in a de facto or cohabitation relationship, or that enter such relationships when one is married. If the prior marriage is for any reason void, the couple is not married, hence each party is free to marry another without falling foul of the bigamy laws. Bigamy is a crime in most countries; when it occurs in this context neither the first nor second spouse is aware of the other, although the majority are involved in plural marriages. In countries that have bigamy laws, with a few exceptions, consent from a prior spouse makes no difference to the legality of the second marriage, considered void.

Before Christianity became the official religion of the Roman Empire and Maximian passed strict anti-polygamy laws in 285 AD that mandated monogamy as the only form of legal marital relationship, as had traditionally been the case in classical Greece and Rome. In 393, the Byzantine Emperor Theodosius I issued an imperial edict to extend the ban on polygamy to Jewish communities. In 1000, Rabbi Gershom ben Judah ruled polygamy inadmissible within Ashkenazi Jewish communities living in a Christian environment. In ancient China, bigamy was a punishable offence. A man, at any given time, could only be married to one woman, vice versa. Issue with the wife enjoyed preference in social status. Most western countries do not recognize polygamous marriages, consider bigamy a crime. Several countries prohibit people from living a polygamous lifestyle; this is the case in some states of the United States where the criminalization of a polygamous lifestyle originated as anti-Mormon laws, although they are enforced.

Ondo-no-seto is a strait in Seto Inland Sea in Kure, Hiroshima between the main island of Japan and Kurahashi island. In the legend, Ondo-no-seto was excavated under the leadership of Taira no Kiyomori from 1164 to 1167 during the Heian period, to allow passage of trading ships for trade with China, but academic research shows. Both old documents research and geological research proved that this straight was not an artificial product; the famous red bridge, called "Ondo-ō-hashi,” crosses the Ondo-no-seto, it is known for the azaleas growing there. Around Ondo-no-seto on the main island side, Ondo-no-seto Park is a popular place to visit. Ondo-no-set is a part of Setonaikai National Park.
