The original eighty two diaries were kept in the National Archives of Japan (the Cabinet Library) and were made Important Cultural Properties in 2003 (however one diary was found not to be Kyokaku's but to have been written by Jinson).
原本82冊が国立公文書館（内閣文庫）に所蔵（ただし、1冊は尋尊の日記が誤って伝えられたものと判明している）され、平成15年（2003年）には重要文化財に指定された。
