This is material from the 19th Judicial Support Architectural Conference of the Architectural Institute of Japan. November 29, 2018 This is material on a rare architectural dispute involving ground subsidence. I went to the Architectural Institute of Japan's office to purchase it (1000 yen?). I used it and no longer need it, but I couldn't bear to throw it away, so I'm putting it up for sale. There is a stain on the cover and a 2 cm pen mark. I hope it will be useful to you.
