Natsu Basho

In Tokyo, the month of May coincides with one of the most anticipated events in the Japanese sporting calendar. From May 10 to May 24, 2026, the Ryogoku Kokugikan will host the May Tournament, also known as the Natsu Basho, one of the six major tournaments of professional sumo. For fifteen days the large arena in the Ryogoku District, in the heart of the capital, becomes the center of a sport that blends ritual, competition and tradition. Sumo is not only an athletic discipline but also a complex cultural system whose roots reach deep into Japan’s religious history. Many of the gestures that precede each match, from the purification of the ring with salt to the ceremonial movements of the wrestlers, derive from ancient Shinto rituals. The May tournament is one of the most important events of the season. As in the other official basho organized by the Japan Sumo Association, the competition lasts fifteen consecutive days and involves hundreds of rikishi, the professional wrestlers divided into several divisions. Matches in the top division, the Makuuchi, take place in the late afternoon and attract the attention of fans and media from across the country. Each day of the tournament follows a precise ritual. Bouts begin in the morning with the lower divisions and culminate in the late afternoon with the clashes between the champions of the highest category. Before every match the wrestlers step onto the dohyō, the circular clay ring, and perform a series of ritual gestures that are an integral part of the spectacle: the throwing of salt to purify the ring, the stamping of the feet and the long moments of concentration before the bout begins. The Ryogoku Kokugikan, inaugurated in 1985, is the modern temple of this tradition. With more than ten thousand seats and a structure designed specifically for sumo, the arena hosts three of the six official tournaments each year and stands as one of the symbolic venues of Japanese sport. The May Tournament of 2026 will bring together the best rikishi in the professional circuit, including yokozuna, ozeki and rising young contenders. For many wrestlers it will be a decisive stage in the race for the seasonal title, while for the public it offers the chance to experience one of the sporting spectacles most deeply rooted in Japanese tradition.
