Although it is considered a cultural heritage by Japanese government, the garden or the park has difficulty to attract foreign tourists because it does not offer foreign language guide tour, even though it does offer English map. Other than its Japanese tea ceremony service and simple traditional Japanese snack service beside the pond, the Garden does not offer other food service.
However, the Garden does have a varieties of trees and other plants, while it does have a 300-year pine tree and a few other old trees. Because most of the trees are rather "short" to fit into traditional Japanese garden scene, when they are compared to the tall trees of Meiji Shrines, visitors have to prepare for the hot weather and sunshine from late April to early or mid September. When trees do not provide shade for the visitors and when there is only limited food service for the visitors, visiting the garden in hot weather can be a difficulty issue for the visitors who have young babies or kids.
The Garden or park does have numerous strict rules for the visitors. For example, although there are a few benches in the garden, visitors are not allowed to sit on the lawn area, which is very different from the front park area of the imperial palace. In such a sense, the Garden or Park seems to lose its purpose of being a garden or park for visitors, regardless who they are, when visitors cannot sit or relax on lawn as they wish.
