Mikan

The type of tangerine we call Clementines, Japanese call mikan. Shizuoka, the California of Japan, was the top mikan growing region. The classic winter treat is to eat mikan sitting on the floor with your legs under a kotatsu, a low table with an electric heater under its surface and a comforter-type blanket on top to trap the heat below. Sitting on floors was never comfortable for me, so I didn't care for kotatsu, but I loved buying mikan fresh from neighborhood orchards.
