Japan, is a very small equestrian nation by European standards with only about 15,000 riding horses registered, and about 4 out of 5 of those are used for pure Dressage. This can be a huge benefit for anyone selling a horse, as there is high demand for quality horse in Japan. A few years ago now, I sold a lovely horse that just wasn't any good at eventing to Japan for Para-Olympic Dressage use at Athens.
Denmark fielded a team in Aachen 2006, but this year is only fielding individuals. The Fins also only have individuals listed and, whilst I can't seem to find any details of the Finnish nominations, I'm assuming it doesn't include Piia Pantsu, sadly. I remember watching Piia at Badminton and thinking wow, what a fantastic rider. She very nearly won on her first attempt losing to Pippa Funnell by 0.4 penality points.
