You should definitely see the Shinto Wedding at Meiji Shrine when you go on a trip to Tokyo. It is one of the most beautiful and interesting places I have been to and I strongly recommend it to any traveler who likes Japanese cultural traditions like myself.
The Meiji Shrine (Meiji Jingu) is the resting place of the first emperor of modern Japan, Emperor Meiji, and his wife Empress Shōken. It was built in 1920 and was officially finished in 1926. In addition to the religious buildings, there is the Treasure Museum which houses the personal belongings of the emperor on display. The garden of the shrine is gorgeous especially in June when the irises bloom.
Today, the shrine is used for Shinto Weddings. A solemn procession of Shinto Weddings is often seen when you visited the place. We were there just in time when the procession started that was led by two priests and two shrine maidens, followed by the couple under a red umbrella, and behind them are their family and friends.
It important to clear the way when the procession started. This is to help maintain the dignity of the event. You may take pictures, but bear in mind to not step into the way of the procession.
The Meiji Shrine is situated in Shibuya Tokyo but is accessible from Harajuku Station. Wear comfortable shoes because the shrine is huge and requires an ample time to explore the place. No entrance fee.
