a sweet potato shop - 芋菓子屋

Just sweet potato's? That's all they sell. I like this sort of image. The roof is that lovely terracotta as well.

Hi Tetsu. Thankyou for your kind comments on my blog. I like ur photos a lot they are sharp & provide a real sense of Japan.

Thanks Tobias and Jon!!

Exactly, the shop sells ohter things, too.
The shop sells not only sweet potatos, but also other things related potatos, I think.
