I was trying to find an authoritative etymology of the word “satsuma” in English. It’s not completely apropos of nothing; the word is definitely of Japanese origin, being the name of a place in Kyushu. In Japanese, the word “satsuma” usually refers to “satsuma imo”, the sweet potato that I wrote about earlier. Satsuma oranges are called “mikan” in Japanese, by the way.
I just had a real “only in Japan” moment. Only in Japan are you disturbed from your thoughts by some guy with a van singing “yaki imo, yaki imo, yaki imo...” through a megaphone.
