Because it is favorably situated and very close to the JR line and subway stations, Mita Library has the most visitors among Minato City libraries. There are many universities and schools in surrounding areas, therefore many students visit this library. The reading room has the greatest number of seats among Minato City libraries; the entire third floor is used only as a reading room. Moreover, there are some seats to which users can bring their own PCs. The Minato Local History Museum is on the fourth floor.
