Whats more important than whether it is 10speed compatible is whether it is compatible with your bottom bracket.
What crankset are you running right now?
What bottom bracket are you using right now? (spindle lenght?)
If it is a square taper bottom bracket then you should be looking for an aftermarket crankset that is intended for a bottom bracket with ISO tapers.
The JIS taper looks very similar but has a different taper angle and although some have gotten them to work well they are not 100% interchangable and you can run into problems with the install and having them staying torqued to spec if you mix the two standards.
