I'd never actually heard of him before, but thought it might be interesting to do a search and find out.
As a spy he was successful for what I would say was several reasons. He firstly had significant knowledge of what he was targeting - the US navy.
He conducted his activities in a region he didn't stand out by race due to large numbers of Japanese in Hawaii at the time and was involved in local gossip.
Yoshikawa spent a lot of time spying and reported this regularly and although in code the Americans had cracked, they hadn't given it much importance... so a little luck was on his side.
As soon as he realised the attack on America all evidence was destroyed. He was picked up on the day of the attack but without any evidence Yoshikawa was only held as a diplimatic prisoner.
That said... he was not "successful" later in life as the Japanese after the war lay much blame on him.
