Not my first trip to Niigata but we had a few first timers go with us. The look on their face when they see the size and colors of koi always reminds me of my first trip. The excitement they have is always welcomed. The end of the trip most newbies start to buy a little better koi in the end. Always worth the trip.
One thing is I always ask them is at the end of the trip what they have learned. Some replies is. The have a lot to learn and or the quality of stuff is no comparision..
Going to Japan is education in itslef even if you dont buy a koi. Just looking at koi is will raise your level of appreciation...
