you're welcome Hye Park Lover
we can take a general view around Shibuya - Harajuku and get an idea of general directions studded with stores, if you are interested.
it would be better than exploring at random.
there is a window saying "表示エリア変更", the second window from top right.
of it, choose "渋谷 (JR渋谷駅)", the third from the top.
then there appeares a map with famous stores data, printable and magnifiable.
dragging up from Shibuya Station leads to Harajuku.
we can see what it's like on the whole.
