Hibiya Park
Prior to World War II, international interest in bonsai was fueled by increased trade in trees and the appearance of books in popular foreign languages. By 1914, the first national annual bonsai show was held (an event repeated annually through 1933) in Tokyo's Hibiya Park. Another great annual public exhibition of trees began in 1927 at the Asahi Newspaper Hall in Tokyo. Beginning in 1934, the prestigious Kokufu-ten annual exhibitions were held in Tokyo's Ueno Park. The first major book on the subject in English was published in the Japanese capital: "Dwarf Trees (Bonsai)" by Shinobu Nozaki.
