If you ever get a chance, try to see Japan in Autumn. The leaves turn that perfect color of red and yellow, the air is the perfect temperature, and the whole country just seems so alive after nearly melting to death over the summer.
My autumn was pretty relaxing, mostly just work, trying not to get stressed, and trying to further adapt to life here in Japan. But it was also very enjoyable! I didn't get to travel anywhere special, but I got to see some pretty amazing things without going far.
