In general yes, especially around major train stations.

Yes, short rides are very common.

Example, from Omotesando Hills back to Yoyogi Shinjuku?

Yoyogi Park near Harajuku Station?

Your example would be fine.

How much do they normally charge?

You can look up rough guides on fares at:-

Your example would be around 2000 yen during daytime. There is a 30% surcharge for late night/early morning taxi fares.

Enjoy your trip!

Thank you so much for your help GC3! :)
