Overview

Tokyo features on the nation's Natural Monument listing with twelve representatives. Ranging throughout Tokyo's southernmost location, its central wards and the western rural cities and towns, the capital's Natural Monuments are heavily tree-centred but also include ancient oceanfront limestone formations and volcanic islands. Here is a simple guide on where to find national Natural Monuments in Tokyo.

Minami-jima Island

The millions of years-old weathered limestone karst formations of the uninhabited Minami-ijima Island just off Chichi-jima Island were recognised nationally as a Natural Monument in 2008.

Minami Io-to Island

Declared a Natural Monument in 1972 and lying as far away from Tokyo as one can be but still be in the capital, Minami Io-to Island is one of the very few islands believed to have never known human habitation.
