In 1993 the professional sumo calendar followed the standard format of six official Grand Sumo tournaments (honbasho), each lasting 15 days. The tournaments were held at the traditional venues:
| Tournament (Basho) | Month(s) | Location |

| Hatsu (January) | 1 – 15 Jan | Tokyo (Ryōgoku Kokugikan) |
| Haru (March) | 13 – 27 Mar | Osaka (Osaka Prefectural Gymnasium) |
| Natsu (May) | 10 – 24 May | Tokyo (Ryōgoku Kokugikan) |
| Nagoya (July) | 12 – 26 Jul | Nagoya (Aichi Prefectural Gymnasium) |
| Aki (September) | 13 – 27 Sep | Tokyo (Ryōgoku Kokugikan) |
| Kyushu (November) | 7 – 21 Nov | Fukuoka (Fukuoka Kokusai Center) |
Notable developments
-
Akebono Taro’s emergence – The Hawaiian‑born wrestler Akebono (born Chad Rowan) captured his first top‑division championship in the March tournament. His success continued throughout the year, positioning him as a leading figure in sumo and paving the way for his eventual promotion to yokozuna, the first foreign‑born wrestler to attain that rank.
-
Retirements – The year saw the retirement of several veteran rikishi, most prominently the former yokozuna Futahaguro, whose departure marked the end of a turbulent career.
-
Promotions and rank changes – Several wrestlers achieved promotion to the senior sanyaku ranks (komusubi, sekiwake, and ōzeki) based on their performance in the 1993 basho, reflecting the gradual shift in the hierarchy toward a new generation of competitors.
-
Stable (heya) activity – Established stables continued to train new talent, while a few new heya were formed under the guidance of retired elders, contributing to the evolving landscape of sumo training environments.
Summary
The 1993 sumo season adhered to the traditional six‑tournament structure and was distinguished by Akebono’s breakthrough as a top‑division champion, signaling a significant moment in the sport’s history. The retirements of notable veterans and the promotion of emerging wrestlers further underscored the transitional nature of this period.
