One interesting area of life in Japan is weddings, and Japanese really take the subject of getting married seriously. One of my first instances of culture shock in Japan happened when I was riding my mountain bike (foreigners always ride mountain bikes in Japan) and came across a sprawling palace that looked like it had fallen out of a time warp from Czarist Russia. Turns out it was a wedding hall, a giant facility created solely for marriage ceremonies and receptions, which are quite common in all corners of Japan. In our prefecture, various companies compete ferociously to capture the largest share of the local wedding market, coming up with interesting themes such as Georgia House, which recreates an Antebellum plantation house from the American South; Lockhart Castle, an authentic castle that was imported from Scotland; and Sharon Gospel Church, a U.S. style Southern Baptist church in the heart of Japan.
You can also get married in Disneyland, naturally.
