Shiori-no-ike (潮入の池), literally “incoming tide”, is a tidal pond drawn from Tokyo bay. The most prominent feature of Hamarikyu Garden, it is the only remaining seawater pond in Tokyo. With the rise and fall of the tide, the sluice gate opens and shuts to regulate water level. The pond is home to several kinds of sea life. The surroundings of the pond are designed according to the mise-en-scène of a traditional stroll garden, being punctuated with artificial hills, trees, shrubs, seasonal flower gardens, stone lanterns, bridges and teahouses.
Hama-rikyū Onshi Teien (浜離宮恩賜庭園), or Hamarikyu Garden, located at the mouth of the Sumida River, is a remodeled garden on the former site of the 17th century Edo-era villa of the Shogun Tokugawa family, which first opened as a public park on April 1, 1946.
