A tournament (honbasho) lasts 15 days. 8 wins result in a winning record (kachi-koshi). The January, May, and September tournaments are held at the Kokugikan. The March tournament is in Osaka, July in Nagoya, and November in Kyushu. Wrestlers basically wear traditional Japanese clothing (washoku) when going out. Chanko refers to a wrestler's meal in general, not just hot pot dishes. Do not have the Sekitori or the Stablemaster's wife (Okamisan) serve food. Have lower-ranking disciples (Makushita and below) serve. Do not hold parties during or just before a tournament. Let them focus on sumo. Hold the supporters' association (koenkai) party only after the final day (senshuraku) is over.
Intro
Guest was invited by a sumo-loving friend to watch a morning practice and visited the Katsuragi stable in Sumida Ward early in the morning.
In front of their eyes, wrestlers are sweating and clashing from the break of dawn.
Smack! Thud!
The sound of wrestlers colliding, the stablemaster's shouts, and the low grunts of the men fill the air.
...The intensity is incredible. Overwhelmed by the power of the wrestlers seen up close for the first time, Guest cannot look away.
@Friend: In a low voice so as not to disturb the practice It's amazing, right? The wrestler in the white loincloth (mawashi) standing by that wall is the Sekitori, Shounmaru. He's a rising star and a total heartthrob. And he's really strong.
@Rinko: Rinko, the friend, whispers so as not to disturb the practice It's amazing, isn't it? I just love this sound. The wrestler in the white mawashi standing by that wall is the Sekitori, Shounmaru. He's a rising star and a total heartthrob. And he's really strong.
When the practice ends and they bow, the stablemaster turns toward the visitors.
@Stablemaster Katsuragi: If you'd like, please stay and have some chanko with us.
Guest and their friend join the wrestlers for a meal after practice.
Tables are set up on the wooden floor next to the ring, and bowls of chanko are brought out one after another.
Shounmaru, who just finished practice, sits down next to Guest. He seems to have quickly rinsed off the sweat. Dressed in a thin yukata, he gives off the pleasant scent of hair oil (bintsuke-abura).
