Where to find nice/cute rugs in Tokyo ?

Hi !

I am staying as an exchange student in Tokyo for a year, and I would like to buy some rugs for my studio. I don't really know where to search though: I've been to Daiso, but they don't have a lot of choices (at least the ones I went to). So please tell me if you have any recommandations of stores where I could find a nice/cute one ! By "cute", I mean I would like it to have some colors (not just grey/brown/black). I don't have a high budget and live in a small space, so I am not necessarily searching for extremely good quality or big rugs, just a nice looking one 🙂
