You can look at a plenty of images and read reports using Instagram. One of advantages of Instagram is “the reality”, although many images are modified for better-looking called as “Bae (kanji: 映え; hiragana: ばえ)”. 

If you want to use "Instagram", 
1) have your account,
2) search what you want to know using “#” and “keyword”. For example, if you enter “#umedacafe” into the search column and click the magnifying glass icon, you are able to get a result of images related to cafes in Umeda.
