Many kanji to choose between
Anyone with a good understanding of kanji and the Japanese language can help you with that. There are many kanji to choose for any syllable, so the options are vast.
Many years ago, my former teacher Ichimura sensei half-jokingly wrote my name in kanji so that it meant: "He who opens his head with his hand, and takes out the brain." That's probably one way of describing my personality...
Another Japanese friend helped me to compose kanji for Stefan, so that it meant: "Throw away riches and security." Alas, I can relate to that, too.
