This item is a <Sumo Yagura Model> produced as a commemorative item for the Autumn Tournament of 1955 (Showa 30). 《Size》 The wooden yagura (tower) itself is approximately 29 x 10 x 10 cm, and it comes in a wooden box of approximately 31 x 10 x 8 cm. This is a rare craft model that realistically recreates the yagura structure on the dohyo (ring) of the Kokugikan (National Sumo Arena) at the time, utilizing bamboo skewers, thin wood, and hemp rope. While there are signs of wear and aging, there is little structural looseness, and it is in very good condition. This is a valuable item that symbolizes the end of the "Four Yokozuna Era" and the transition to the "Tochiwaka Era," representing Showa sumo history. In this tournament, the "Four Yokozuna" - Chiyonoyama, Kagamisato, Yoshieyama, and Tochinishiki - were all present, resulting in an extremely rare ranking composition in sumo history. The yagura's signboard features the names of these Yokozuna, as well as the names of Ozeki, Sekiwake, and Maegashira of the time, such as Wakanohana, Asashio, Ouchiyama, Mineyama, Haguroyama, and Tsurugamine, making it a commemorative item that provides a comprehensive view of the golden age of Showa sumo rankings. This ranking group is also valued as a "three-dimensional ranking material" of Showa sumo. The Autumn Tournament of 1955 was a historic event where Kagamisato Kiyoji won with 14 wins and 1 loss, and it also marked the beginning of the "Tochiwaka Era," with Tochinishiki and Wakanohana taking on the next generation. Chiyonoyama was entering his prime, Yoshieyama was approaching retirement, and the structure was such that heavyweight wrestlers like Asashio, Ouchiyama, and Haguroyama supported the dohyo. This model, which includes all the names of these wrestlers, is not just a commemorative item but also has value as a cultural historical material that allows for a three-dimensional understanding of the wrestlers' power dynamics and ranking composition. The design of the yagura model features a taiko (drum) stand at the top, with the pillars tightened with hemp rope, creating a sense of tension reminiscent of the actual dohyo yagura. It is a handmade reproduction of the yagura architecture of sumo festivals, dedication sumo, and regional tours, and the techniques of craft artisans of the mid-Showa period can be seen throughout. It is also dignified for ornamental purposes and has a strong presence even when placed in a Japanese-style room or study.
