heres some youtube stuff you should watch.
dynamite kid vs tiger mask. these guys were way ahead of there time. they did a lot for the junior division......the most awesome matwork. remember this is in like early 80's. most of the clips are from like 81-83 i think.

misawa v kawada. these guys were the greatest in the 90's. had awesome feuds. the pinnacle of japanese strong style wrestling. its a clipped match. the sequence of elbows vs kicks back and forth they always have is amazing.

kobashi v dr death williams. this match is insanely stiff. from the 90's again. AJPW had so many stars in the 90's it was ridiculous the ammount of 5 star matches that came out form that time. this is a whole match. requires patience to watch. but you should see the ending.

misawa v kobashi (its labeled wrong on youtube). another long match. this is much later in their career (2005 match i think). but they don't give a fuck. they just totally go for it. the story behind this is that kobashi(black trunks) has never beaten misawa for the championship in 7 years.

i also used to love the high flying stuff. it was pretty much all i used to watch. i used to watch all the juniors in japanese wrestling, benoit, guerroro, lyger, tiger mask, great sasuke. i never really cared for the heavyweight stuff.
but then i gave it a chance. and the japanese heavyweight matches are just fucking awesome.
if you've got like an hour or so you should just watch all those youtube vids. theres plenty of it on youtube now.
