Ikura-do Cave is a well-loved sightseeing spot for travelers far and wide because it is associated with a tragedy of love and has a shrine dedicated to the legend. According to the story, a young woman took her own life on the news that her love went in search of a princess in another land.

A 1200 meter long, 240 meter high cave system with staggering height variations throughout its ceiling, Ikura-do is a safe trekking option in Niimi. Taking about 40 minutes to complete, trekkers are amazed at the towering stalagmites, hanging stalactites, professionally lit rock formations and pools of water that have collected in natural basins. 

Don’t forget to have a look at the 70 meter high waterfall that emerges from the limestone rock face. It would actually be hard to miss since it gushes past the main entrance.

The facilities surrounding Ikura-do have a throwback feel to them. Some call it “Showa era” but you could just call it old Japan. Everything is utilitarian yet elegant at the same time.

After completing the course have a meal at the local eatery and marvel at the impressive  limestone cliffs that dominate the area. There is also a gift shop that sells items that will bring back memories of the area for years to come.

There are other caves and rock formations in the area that are worth seeing so check them out. For example, the slightly smaller Maki-do is not far from Ikura-do and is just as popular. You could easily explore both cave systems in one day.
