Asashoryu, who made his debut as a yokozuna in March, occupies the prestigious east slot for the first time as the Japan Sumo Association (JSA) released its rankings for the upcoming Summer Grand Sumo Tournament on Wednesday.
The 22-year-old Mongolian grand champion will look to get back on track after finishing a disappointing 10-5 last month and failing to claim his third consecutive title.
Chiyotaikai, who will be bidding for promotion to sumo's highest rank after claiming his third Emperor's Cup with a 12-3 record at the spring tourney, sits in the top east ozeki position for the May 11-25 meet at Tokyo's Ryogoku Kokugikan.
