Are you sure you got that right Peter? I got my Shodan last year, and I vaguely remember it being double that, with half going back to the dojo. The amount that you quoted would be the amount that gets sent to Aikikai. I think...
I am certain that the amounts stated are correct. I send the cash via 現金書留 and the diplomas come quite quickly. I mentioned in my post that the Aikikai have a system for remitting half the costs to the organization and you can see that the amounts quoted for the Danish Aikikai are almost precisely double what we pay.
