Myōken Island

Myōken Island is a river island within the Old Edo River, surrounded by industrial structures and a marina on Tokyo's eastern side. The site combines natural features with modern port facilities and is crossed by several pathways.

Records from 1362 document the transfer of a religious statue from Myōkaku-ji temple in Higashi Ichinoe village to a shrine on this island. This event marks the beginning of the site's spiritual significance in local history.

The island's name comes from Myōken, a deity linked to the North Star and Big Dipper in Japanese spiritual traditions. This religious connection remains part of how locals understand the place.

The island is accessible via Urayasu Bridge; a walk is required from there to reach the entrance area. It is advisable to wear comfortable shoes and exercise caution during wet weather, as the pathways can become slippery.

This is the only naturally formed island remaining within Tokyo's 23 wards and retains intact natural features despite its location between industrial facilities and port operations. This rarity makes it a remarkable geographic exception in the heavily urbanized surroundings.
