Where can I buy a sugegasa?

Where can I buy a sugegasa in Tokyo close to Akihabara-Ueno? and by the way; is this used currently by anyone in the cities? -or at least at summer festival- or is it just a souvenir for local people also?

Some souvenir shops in Asakusa?

I think it's used for ‚¨•Õ˜H(oHenro; pilgrims) in Shikoku region today.

Or Buddhist priests like this in the cities even in Tokyo.

Suge-gasa is not in common use. Just for souvenior or for cosplay. Yet you can see some farmers in the country side wearing this in the rice field. City people do not put it on.

Amazon is selling them on web.
