Not a bad place to first start your career - Mitarbeiter (anonym) bei Rakuten: Mitarbeiterbewertung

Its hard to make new things happen, as there is so many people above you who doesn't have the time to take care of such things. Once you are in the position for more than a year and learnt what it is all about, its hard to visualize/imagine what you can/want to do next, (for the reason above, partially). Yes, it is up to you and your effort to make things happen but the environment isnt really there to help you keep up with your motivation. Thats probably one of the reasons why people leave very often.
