I wrote that my friend got hurt in Whistler when skiing down. At that time, one of the rescue staff was surprised that we didn't wear helmets. He advised me, "You'd better wear a ski helmet if you want to ski down a 'black' run." 'Black' means the most difficult ski trails at Whistler. I thought that he was right and to tell the truth, I had wanted to get one since four years ago. I looked for one in Whistler four years ago, but couldn't find a nice one. I looked for one this year, but I couldn't find one. The time of the year might be bad. It was the end of March or the beginning of April, i.e. the end of the ski season. Even the biggest one found in Whistler was small for me. The upper temporal part of my head touched the inner part of the helmet. I decided to look for one in Japan.
I found various big helmets on the internet, but I had to try them on. In order to try them on, I flew to Tokyo. Then, I called my eldest daughter and her fiance and enjoyed walking in a historic and modern district.
Do you know the mountain in the first picture? It was taken from the plane. The second one is the gate of Yasukuni Shrine. The next one is the tallest broadcasting tower in the world called "Skytree", one week before its opening to the public. The last picture is of my ski helmet.
