This hilly district, somewhat reminiscent of San Francisco, has since 1887 been home to the expatriate population which deserted the port area. This cosmopolitan heritage is visible in its buildings: twenty or so ijinkan (Victorian-style homes of European traders), twelve of which are open to the public, winding streets, European-style cafés, Catholic and Reformist churches, a mosque, a synagogue and even an Indian Jain temple. Its other claim to fame is that it is built on a slope, which is very unusual for Japanese cities.
