In Shibuya and Shinjuku, I've found that these 2 places got a lot of similar shops such as LABI , BIC , Uniqlo and a lot more. Which place got better shop? I'm gonna go to Tokyo next week. Thanks !
The shops are quite the same, I think for most of the time both shops have same stocks. Decide the place by what restaurants you want to go or what else you want to see :)
I think Shibuya is better than Shinjyuku.
Because there are many restaurants & newest shops there. Also not only about shopping.
You can take a most famous intersection's photo.
Furthermore, there are many volunteer staffs who have sign with "May I help you?" here and there. All of them can speak English and help foreigners.
i.e. Shibuya is the most kind town for foreigners.
I think Shibuya is better for shopping :)
I hope you will enjoy in Japan!
