I think I found fabric heaven!!!
There are 85 fabric shops packed into one little area of Tokyo called Nippori.
I probably managed about a 10th of the shops in two and a half hours. At that point I just needed to calm down, breathe and have some cake. I had literally excited myself out.
I was after some very specific Japanese fabrics but you can really find anything under the sun on this street. I kept straying and had to reel myself back in. I did end up buying some gorgeous Indian cotton which was totally irrelevant to what I needed.
Part two of my Tokyo trip coming soon!
