Try living somewhere besides Tokyo, somewhere a little more rural. Life in the countryside of Japan can be very relaxing and slow-paced, not at all like the big city. It was fun to visit the big city every now and then, but I was happy to be living in the countryside.

Also, time back in the US (or wherever a foreigner's home is) tends to ease the frustrations, stress, and difficulties of living in Japan, and emphasize the fond memories, the memorable experiences, and cause you to miss a lot of the things you enjoyed about Japan. (Conversely, while in Japan, you'll probably feel the same about your home country). That's only natural. "Absence makes the heart grow fonder", as the saying goes.
