There are many long-established good Japanese buckwheat noodle restaurants in Kanda. "Kanda Yabusoba" was founded in 1880. Soba is Japanese brown noodle made from buckwheat flour. Generally, it is eaten cold after being dipped in a soy-flavored sauce. Kanda is also famous as a city for secondhand bookstores. You should take a walk to look for the books you like after eating Soba.

Hawaian inspired tiny tiki bar, just a round corner form Shimokitazawa Station. Super nice decoration / owners personal skateboard collection, wired plants etc. Best Mojito in Tokyo! 

Skip the museum itself if you want, as the garden of this place is the nicest part. Green and quiet, you will forget you are in the middle of Tokyo

Around the museum there is space to stroll, and some shopping. It's a place you can enjoy without getting tired. The museum is approx 50 min from Tokyo.

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.
