Boy your a hostile little cuss aintya ? Heres my last link on the glory filled History of Japanese tanks in WW-2. http://www.scribd.com/doc/7373250/15 I admit the IJA tanks did well until they faced other tanks or anti-tank guns. 
Go ahead, get the last word in. Guys like you always have to get the last word in.
i haven't gotten hostile yet and i'm sure i won't be the one to get the last word in. did you know that in old japanese traditions like bushido, there was glory and honor in death? as far as the japanese were concerned their tanks helped provide many glorious victories.
i'm guessing you didn't fully read your last reference, if you had your continued sarcasm wouldn't be so blatantly obvious. before i quote a passage from your last reference i suppose just for clarification in case it escaped you early on in this discussion, not one person said japanese tanks were as good as panzers, tigers, t-34s, or shermans. all of which incidentally also suffered losses to other tanks and anti-tank weapons, as you so conveniently attempt to overlook.
before 1942 when japanese tank production dropped heavily, japanese tanks were very capable against other early tanks like the m3 stuart, bt-5, t-26, hotchkiss h-35, vickers mk-e, etc... in fact your last reference states of the japanese invasion of singapore on page 18: "singapore fell on february 15, due in no small measure to the effective use of tanks." the author goes on to state further down the same page: " the british 2nd royal tank regiment fought a series of costly rear guard actions in burma. by the time the survivors of the unit reached british lines in india, only one stuart tank remained in action." i don't know about you but, that doesn't sound very much like "piss poor japanese armor" to me.
what is very amusing is that if we all followed your logic, considering construction, mechanical reliability and numbers lost in battle, the t-34 would be the worst tank ever put on the modern battlefield, but strangely enough russia continued to produce the tank for decades after the war.
