O Taki is a stunning double waterfall that is found way off the beaten track deep in the Arai area of Myoko City. Even most of the locals havent visited or even know about this waterfall. You can reach the waterfall by car and there is parking available but the best way to get there is by train to Arai station and then take a bus. Check the website link for details.
The walk to the waterfall takes around 1hr and can be made by all ages. You should take some snacks and drinks with you because there are no shops nearby.
The walk to the waterfall has some stunning panoramic views of the Myoko mountain range.
This is a highly recommended place to visit if you have the time to travel there.
