In 1974 he searched for and found Hiroo Onoda, one of the last remaining Japanese holdouts who had refused to surrender after the end of World War II.
Onoda described this moment in a 2010 interview: "This hippie boy Suzuki came to the island to listen to the feelings of a Japanese soldier.
After extended conversations, Onoda agreed to wait for Suzuki to return with his former commanding officer (who was now an old man working in a bookstore) to give the order to surrender.
He turned over his sword, a functioning Arisaka Type 99 rifle, 500 rounds of ammunition and several hand grenades, as well as the dagger his mother had given him in 1944 to kill himself with if he was captured.
After finding Onoda, Suzuki quickly found a wild panda, and claimed to have spotted a yeti from a distance by July 1975, hiking in the Dhaulagiri range of the Himalayas.
