Okay. I found it. I now had some time to fire up Illustrator and I must say there is an option that gives a mix between traced-around and centered lines. So I have to admit I was kind of wrong. Well. Fully wrong. So much for blind answering a question about an underexplored option... :-) Take a look at this screenshot (it is in Dutch), the secret lies in the 'fill' ('vullingen') and 'stroke' ('streken') tick boxes. You could try to use only stroke. The Kanji in your example looks rather thick for this kind of translation, but you can try.
