Harajuku (?? in Japanese) is a station located between Shibuya and Shinjuku on the JR Yamanote loop line around central Tokyo. Many people get off the train at Harajuku Station to visit such popular spots as Yoyogi Park, Meiji Shrine and Omotesando, a boulevard of luxury brands and other high-end shopping experiences.
It's possible, just depends how long you want to spend at places. Things like hachiko and the crossing will take just a couple minutes. Then get on the train and go to harajuku. For us, this was a very short walk, got some cotton candy, and then we had felt we had seen what we needed there.
If you're young and adventurous you might like Shibuya more. If you are around retirement age perhaps you might prefer Ginza. But it might depend more on actual hotels.
Although the temple and shops close around 5 p.m., the temple, pagoda and the street are illuminated after sunset. It is worth visiting to see the street art, Asakusa Emaki, on the shutters of the closed shops without crowds.
