How much are the fees?
I know that 5th Dan is Y70,000
Looking at something that was floating around last year (with the exclusion of 1st Dan as you pay registration at the same time) the fees fit quite nicely into Dan level x £100 i.e. Nidan £200, Sandan £300 ... Y70.000 is £500 give or take. Coincidence? Probably!
But hey, the upper echelons are a long way off for me. So no need for me to worry about the finances for a while. Still, I was talking to a colleague the other day that is coming up to her Shodan in some form of Karate and her grading fees (made up of various bits and bobs) come to about £500. She was quite shocked when I shared mine was <£200.
If you personally see a value to having something you pay the sticker price don't you? If not, you walk away.
