Where to buy big size socks ? 31cm

I have only 2 pairs of socks left. AHHHHHH help me (T_T)
My feet size is 31.
I can't find my socks anywhere in Japan. I have found 2 stores in Tokyo that sell them but they wanted 800yen for 1 pair. A little outrageous don't you think?

any help is greatly appreciated. I would prefer a store then internet shopping.

Try Sakazen, Their site is only in Japanese, but you can check the map for the closest shop to you. I'm sure you can find your size & the prices are pretty good.

I have checked out there and they didn't have much stuff but maybe I'll go again.
