In nearly every restaurant you go to in Japan, they will have samples of their restaurant’s food on display in the window. 
This week I went to Kappabashi, a street in Tokyo that specialises in kitchen products. There were whole shops that sold nothing but kitchen sinks, and other dedicated to plastic cups and waribashi.
But the best shops are the ones that sell plastic food! If you are a Japanese restaurant, you can bring pictures of your dishes to these shops and they will make perfect plastic replicas for you to put in your shop window. You can also buy the dishes they have on display there. でも、とても たかかったです！！！
Each of these pieces of てんぷら were about ¥2000!
I bought a couple that weren’t too expensive…やきそば
DIY らめん: This one you have to construct yourself… It comes with the pieces and you have to heat the liquid and set all the pieces in it… How hard can it be?!?
And the best news… these shops have online stores! Check out:
