Wavdash Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo, President: Kazumi Shimoyama), which operates the community-created regional support site 'Seikatsu-guide.com' (https://www.seikatsu-guide.com/), has announced the top 5 of its 55th Minna no Ranking: 'Mysterious Places Ranking'.

This ranking was determined by having Seikatsu-guide.com members vote on 'mysterious places' carefully selected by the Seikatsu-guide.com management office—places across the country that make you wonder 'why is something like this here?' or give you the feeling of sensing something mysterious when you go there.

The number 1 spot this time went to the 'Yonaguni Monument (Submarine Ruins)' in Yonaguni Town, Yaeyama District, Okinawa Prefecture.

Off the coast of Yonaguni Island, at a depth of 25 meters on the seabed, sleeps a massive stone structure shaped like stairs, passages, and altars, which seems impossible to be a natural formation. The stones, beautifully crafted as if they could only be the work of human hands, make one wonder if they are traces of an ancient civilization that once flourished and is now lost.

We received comments such as, 'Because I feel a sense of romance in the fact that something rests on the seabed without us knowing whether it is man-made or not' (Male in his 30s), and 'I was drawn to the submarine ruins. I am curious if it is man-made. I want to dive and actually see it' (Female in her 50s).

We also received a comment from a representative of the Planning and Finance Division of the Yonaguni Town Office, which won 1st place this time.

■ 1st Place Award Comment

We are very pleased that so many people voted for the Yonaguni Monument in the 'Fascinating Mysterious Places Ranking'.

■ About the Yonaguni Monument

The Yonaguni Monument has a shape that makes it easy to imagine people actually living there. Whether it is an artificial 'ruin' created by people who lived on Yonaguni Island, or a natural 'topography' created by the strong tidal currents of the Kuroshio Current passing through Yonaguni Island, it is a mysterious place that fascinates everyone, so please come and see it with your own eyes to make sure. It is a famous spot for diving, and even those who do not dive can actually confirm it by boarding a glass-bottom boat.

Yonaguni Town also holds various events.

The Harvest Festival is held on an auspicious day after June every year and is the liveliest festival among annual events. It gives thanks and celebrates the good harvest of that year, and prays for a good harvest the following year. Each village on the island raises a flag standard, and stick dances and traditional dances are performed. Also, once every two years, a large tug-of-war is held, dividing the participants into east and west.
