This pot was created by Tanomogi Keikichi, who worked as the Minister of Communications and Transportation and mayor of Tokyo in the early years of Showa era (1926). Tanomogi had a residence in Owada (present day Minuma Ward), which is near Omiya Bonsai Village. He kept many bonsai there and was known to have had a great love for Ezo spruce. He would also visit Omiya Bonsai Village on occasion. He built a kiln in his residence in 1932 and fired this piece there. He named it Komeisan, planted an Ezo spruce in it, and loved it dearly. It is said that this piece is very fitting for Ezo spruce because it absorbs water well and evaporates quickly.
