Tetsuzo Iwamoto finished the war credited with approximately 80 planes destroyed in China & WW2. He had almost 8 years of combat under his belt, had flown against a myriad of enemy & downed a large share of them as well. This makes him one of the most experienced fighter pilots of all time.
His own writings, which were found after his death, have him claiming 202 planes destroyed, 27 unconfirmed destroyed, 26 shared destroyed & 2 destroyed OTG [on the ground].
The Japanese were probably the biggest over-claimers* of WW2 however and since Nishizawa was considered "Top Dog" by the Japanese at the time, I consider the estimate of 80 to be somewhat high. No doubt others consider it far too low.
Like many Japanese veterans, Iwamoto did not adjust well to Japan's defeat. This was not helped by the fact that he was "blacklisted" from most employment opportunities & had turned to alcohol.
On 20 May 1955, after a series of bad surgeries, he passed away, his wife claiming his last words to be, roughly, "When I get better, I want to fly again."

[* It should be noted that the over-claiming was probably a result of poor record keeping techniques as opposed to pilot boasting]
