You might want to pick up a Feather AC. Yes, I know it isn't the same EXCEPT for the actual shaving motion. Some folks prefer this style, others don't and it would be a cheaper/easier way to figure that out. This would let you try the Japanese style without having to worry about the honing idiosyncrasies of the Iwasaki (which are not insignificant). They show up in the B/S/T areas pretty regularly.

Enjoy,
