Overview
Mikadobashira is a small rocky pinnacle of about 0.15 hectares standing in the Genkai Sea off Munakata City, Fukuoka Prefecture, and is one of the component parts of the UNESCO World Heritage property, the Sacred Island of Okinoshima and Associated Sites in the Munakata Region. Rising near Okinoshima, the column-shaped rock evokes, as its name suggests, a gatepost to the sacred realm, standing on the sea as if guarding the holy island. It is not a place to land and tour but a rock of faith to be looked up to from afar.

History
Munakata-Okinoshima was the setting for ancient rituals praying for safe voyages from the 4th to the 9th century and was inscribed as a World Heritage Site in 2017. Mikadobashira is counted among its component sites, preserved as a reef that, together with Okinoshima, forms a sacred seascape. Its name, meaning sacred gatepost, suggests that the rock has been understood as a symbolic entrance to the island of the gods.
Access
The rock lies near 34.23°N, 130.11°E, offshore from Munakata City. As part of a sacred World Heritage domain, public landing is not allowed and close viewing at the rock is not permitted. The customary way is to venerate it from afar from the Munakata coast or from a boat on routes overlooking Okinoshima. Please confirm the latest information on whether distant worship is possible and on boat operations through official sources.
Best season
Spring through autumn, when the sea is calm and the view reaches far, suits distant viewing of the rock from a boat or shore. Because the Genkai Sea can change abruptly, it is best to plan distant worship or nearby touring without strain, in line with the day's sea conditions.
