Asakusa is good place to buy Japanese things from Tokyo
Asakusa is well known place for the tourist. It is fun to go shopping and eating in Asakusa as well.
There are many shops in Asakusa and lots of shops sells Edokomono.
Edokomono means Tokyo traditional small peace of hand crafts.
My favorite shop is "sukeroku助六" in Nakamise Street( when you go to Sensoji temple, you can see this shop around the corner from the temple)
They sells Japanese traditional hand craft toys and they are adorable.
