Kendo equipment is somewhat different and can be very expensive. Try here..
http://www.e-bogu.com/The Bokken is more for self training all alone type practice. Not that a bokken isn't used 1 v 1 but they tend to splinter and or break after prolonged use. And can be very dangerous to participants and bystanders when this happens! If you use it for 1 v 1 be prepared to replace it often. And if you ever get hit with one (which should NOT happen if you're doing it properly) you may choose to avoid future 1 v 1 practice with bokkens.
NOTE: Some will practice with a bokkens for live blade demo's!
If you wish further info on bokkens I have a pretty good listing. Prices range from a few dollars to way up there! The cheaper ones are usually of the more brittle types of wood. The materials used in bokken constructuion vary widely. Many that have invested in the higher priced bokken (over $100) would NEVER use them in a 1 v 1.
Strength training can be done with the Suburito. Although some use this exclusively over a standard Bokken.
NOTE: AVOID any sword called stainless steel!!!!!!!!!!!!!!!!!!!!
The chromium makes them TOO BRITTLE for actual use!!!!
They will crack and break!!!
You could find your own blade has become very harmful shrapnel.
