Mr. Yoshihisa was very accommodating during my tour of the Metropolitan Area Outer Underground Discharge Channel (also known as the G-Cans facility). I had short notice before the tour, but Mr. Yoshihisa was quick to respond with his availability for being a translator, since the public tour was only in Japanese. Translation was reliable during the tour. I appreciate his recognition of my interest of the facility.
Thank you Roger for your kind review. It was indeed a very special and exicitng experience, especially on a day just a few days after big rainfall. We were able to experience the real functioning of this underground donjon.I am so exitec that I was with a person like you, so enthusiastic to know many things about this facility. Also I felt very honored to know that my translation helped to know better about this rare underground shrine. I hope we meet again. Thank you.
