Hello Paula,
I would very highly recommend taking Econest's Japanese Timber Framing course at Ashland, Oregon. Check it out if you haven't already at
http://www.econesthomes.com/natural-building-workshops/overview/timber-framing-workshop/
Unfortunately, it says its full but I wouldn't let that stop you. Call or email Robert or Paula Laporte and tell them your interests and I'm sure they'd find a way.
I took this course in Spring of 2011 and found it very useful and motivating. Dale Brotherton is not only one of the finest Japanese carpenters in this country but an excellent teacher as well. Check out his work at

I hope these links help.
