Hi Mike,
The breeder is "Takefuji", and Yorijo simply means "Koi Farm". Shuuichi (or Moriichi...Japanese names can have more than 1 reading :smt012 ) Takefuji is the name of the breeder, but I've yet to meet him personally. There seems to be a lot of interest in showa breeding in central Kyushu these days.
Although it's a mammoth task to compile that breeder data on
all koi in shows (it's not included in entry forms for obvious reasons), the information for some of the koi can still be had by querying the owners or people that know. Obviously, you can't contact hundreds of people asking for the details though. :roll:
If there's any specific koi that you'd like details on, please post your queries here and I'll see what I can do. After all...that's one of the things that this board is for! :wink:
