My day in Kyoto was a blast. I met Takeda in the train station since we both traveled from different directions and Mr. Imanishi picked us up there and took us to his shop.
When I was at Mr. Imanishi's shop with Takeda we decided to go into his basement and poke around. I grabbed one stone that was wrapped in newspaper and asked Takeda if he could tell me the date and he told me 1974.
Mr. Imanishi said that most of his remaining stock was mined at that time.
Anyway, we pulled out some cool stuff. There were some huge natural stones wrapped in blankets that we pulled out. These are not going into our garden but they were super cool. Take a look. This is an oozuku. Most likely the largest one on the planet.
