I introduced Umi Yama Aida ~In Between Mountains and Oceans~ last blog. I also touched about in the forest of Ise, there is an area of super high frequency as much as African rainforest, and it is closer to experiencing “feeling” rather than “listening”, Mr. Ohashi of the brain scientist taught.
I do not hear it, but there are sounds, today is about what I remembered when thinking about such a thing.
