Kanji tattoo?

I often see people with kanji tattoos, so I like to surreptitiously try to read them. (練習のためですね。　笑) Sometimes the kanji is missing strokes or even reversed, or there's a string of kanji written in different styles—楷書、行書、etc. Since my phone (携帯様) is always with me, when I don't know the kanji I can look them up. So last night at the store I saw a guy with a giant kanji tattoo on his calf—鮨 (sushi). I can understand having a tattoo of something very meaningful, but sushi?! Can one be so fond of sushi as to have its name tattooed on one's calf? Maybe. Or maybe he's a chef at Morimoto. Or something. 人生って、不思議なものですね。
