If you are into "Midnight Diner"-esque night experience but not into a crowded Shinjuku scale, then this is a good alternative. Smaller and much more laid back.

This cave at the foot of Mt. Fuji is located in the spread of volcanic rocks, surrounded by sea of trees where compass is no use. The temperatures drop suddenly, and you will not be able to stay inside the cave for long. However, the explorers will go further inside seeking for the bats flying around. It is highly recommended to visitors of the sacred Mt. Fuji .

This mountain is known as one of the top one hundred famous mountains in Japan. And is one of the highest mountains in the Tokyo area. I went mountaineering at the end of last autumn, and felt cold at the summit. The views changed as winds pushed away thick clouds, and I felt that winter was just around the corner. Scenery is breathtaking. It is recommended as a mountain comparatively easy to climb.

TORAYA is known for one of the best Japanese traditional sweets which are made from the organic beans from Hokkaido. You can get Toraya's famous Yokan sweets with well-designed packaging and wrapping. One of my favorite place in Ginza area.
