This park is so beautiful and the best part of it is the japanese garden area. Its so traditional and what you want to see when your on a holiday to japan! great place to take some pictures and have a breather from all the crowded streets.
When you start to feel overwhelmed by the size, speed, and intensity of day-to-day Tokyo, the gardens are an oasis of natural calm. I was especially fond of the Japanese gardens and the Tea house. The large open spaces of the lawn areas are also a great way to decompress from the claustrophpobic urban canyon of Shinjuku. Highly recommended.
This is a great garden to visit during cherry blossom season. If you can find a place to sit down and have you alcoholic picnic, the park is beautiful and variegated. It closes surprisingly early (especially since the hanami parties in other parks go until last train) and remember that it is closed on Mondays. I've tried to go to this park twice and not been admitted, once on account that it was Monday, and the other time, because it was 4:00 and the park was closing soon. Other than having somewhat inconvenient times, the garden is wonderful.
This garden is a nice escape from the bustling Shinjuku area. The garden, located near Shinjuku station, is easy to get to with many signs pointing the way. It costs only 200 yen to enter and you receive a recyclable ticket which prints the date on it in a reusable fashion (See the photo in the photo section). I liked this reusable ticket and the environmental friendliness of the park.
Upon entering, the Japanese traditional garden is ahead. As it is a typical Japanese garden, there are some nice bridges and ponds. However, this garden is different in that it has a pavilion which is built with influence from Chinese architecture. It can been seen immediately that it doesn't look like the traditional Japanese architecture. It is called the Taiwan Pavilion, or Kyugoryotei in Japanese.
There is also a lot of open grass area perfect for sitting down to relax and chat with friends. However, you cannot bring alcohol into the park so you will just have to enjoy conversation as it is. I went just as some of the early cherry blossoms were blooming so it made it especially nice to sit under the trees and look out over the garden.
For 700 yen at the tea house, you can enjoy a cup of Japanese tea and a traditional Japanese sweet.
Shinjuku Gyoen also includes sections called the English Landscape Garden and the French Formal Garden. The English garden is basically a field of groomed grass, and actually looked quite similar to Hyde Park of London. The French garden contains rows and rows of roses. Unfortunately, they were not in bloom when I was there. I will definitely be going back later this spring or early summer to see them.
Overall, while I don't think this is the best garden in Tokyo, I think that it is a nice stop if you are in Shinjuku and want to get away.
