Last Friday, several members of the Ireland rugby team, including Clan Healy and Rory Best, visited Isegahama stable to watch a training session.
It's unusual for outsiders to be allowed into a stable during tournaments as the rikishi involved understandably want to avoid distractions, but also because training itself is lighter and shorter, and fewer wrestlers are present.
Stables don't want guests to come away feeling disappointed or thinking sumo training is easy so they tend to restrict visits to inter-tournament periods.
