Kogetsu is a basement Japanese izakaya a three-minute walk from Shimokitazawa Station's east exit and from Keio Inokashira Line's north exit. It serves sashimi, Japanese-style broth omelet topped with sea urchin, large rock oysters, and seasonal dishes. Private rooms, semi-private rooms, and counter seats allow visits alone or in groups. Several kinds of sake and shochu are available, and lemon sour is on the menu.
