This article explores the legal, cultural, religious and social implications of marrying multiple wives in Japan. It explains that polygamy is not legally recognized by the Civil Code of Japan and those who practice it may face fines or jail time if caught. The cultural views on polygamy vary depending on region and social class but generally speaking it is seen as something outside of traditional values and beliefs about marriage in Japan. Additionally, many people view polygamy as being unfair to women since it allows men to take advantage of their position by having multiple wives without providing equal rights or benefits to each partner involved. Finally, religion also plays an important role when discussing polygamous marriages since most faiths frown upon such arrangements based off belief that monogamy should be upheld as part of God's plan for humanity.
