Generally, it isn't wise to spend hundreds of dollars on rifles or anything else that you don't really understand.
It's always best to spend money on books before spending money on milsurp rifles, any type of milsurp rifles, even $99 Mosin Nagants.
What's the rush? Do your homework first, shopping second, unless you have money to waste. Even then, waste it on books first, rifles second.
Start with this book Amazon.com: Military Rifles of Japan (9780962320873): Fred L., Jr. Honeycutt, F. Patt Anthony: Books The price might seem high, but if it keeps you from throwing hundreds of dollars away on a piece of junk it will be well worth it.
One of the best books I own about any type of milsurp rifle is the "Type 38 Arisaka" by By Francis C. Allan and Harold W. "Ogesan" Macy BANZAI© Special Project #8 - The Type 38 Arisaka
Not as comprehensive as the Type 38 book but still useful is the Type 99 book by Doss White & Don Voigt WTS: T 99 Arisaka Books - sold out! Despite the thread title there might be a few copies left for sale.
You can go on Gunbroker.com and see what Japanese rifles sell for, but unless you know something about the rifles and what makes one more valuable than another the price information won't make much sense. A $250 Arisaka might be laughably overpriced or the deal of the century, but you'll never know if you don't do your homework first! ;)
