Thank you for your comments. It may not be possible to respond to all of them, but I will respond little by little when I have time, so please be patient.
Thank you for your comment. I was surprised to find out that this video has viewers overseas. I've quickly added an English translation using Google Translate, so try turning on subtitles. The translation isn't the best, but I've made sure that the names of the stones are correct, so I hope you enjoy.
