This article looks at the history and practice of arranged marriage in Japan, also known as "omiai" or "miai". It has been practiced since the Edo period (1603-1868) but has seen a decline since World War II due to changing social norms and values. There are two main types - formal omiai (formal meetings) and informal omiai (informal meetings). Arranged marriages have many benefits such as providing stability, allowing couples to get to know each other better before making a commitment, reducing financial burden on families, and providing support from extended family members. However, there are also some challenges associated with it such as pressure from family members or difficulty finding compatible partners.
