Yoyogi is one of the biggest parks in Tokyo with a 550,000 sqm area. When you walk into the park from Yoyogi metro station, there is a very long path crossing the park until Harajuku. Along this path it is possible to see the huge ‘sake’ barrels on the left side, which are kept there as a memorial of Meiji, and the wine barrels on the right side that are presents from France to the Meiji family.
It is a great park to spend a day in at the weekend, and also to visit the famous Meiji shrine. This visit could also be combined with the Harajuku region, which is also most fun to visit on Sundays.
