トムネコゴ (Tomunekogo) is a small, cozy and rustic cafe alongside the entrance to Inokashira-Koen in the Kichijoji area of western Tokyo. It's located on the first floor of an old Showa-Era (postwar) apartment building that faces the park, although the cafe itself only opened 3 years ago.
Going through the narrow entrance you have to squeeze left in front of the tiny kitchen (right away you realize this was once an actual apartment) and into the seating area of the cafe. The decor is wooden and antique; you'll notice in the center of the room, in front of the bookcase filled with records, a beautiful old gas heater with a kettle of of tea placed on top. It's one of those little touches that always makes a cafe more welcoming.
The music is kept a softer volume than many other cafes; the owner says he wants the atmosphere to stay mellow with quiet conversation and mid-tempo jazz, so even though there's alcohol on the menu don't come here for a rowdy session. On our visit there he was playing some MJQ, then a Ben Webster ballads album, both of which sounded perfect in that space.
The entry has a small bookshelf and wooden 'Open' sign easily visible from the road along the park, just one minute walk from Inokashira-Park station on the Keio Line. See here for more pics of Tomunekogo.
Come out of Inokashira-Park Station on the Keio Line and turn right along the park. Just two minutes up on the left side you'll see an old grey apartment building with the entrance to the cafe on the 1st floor facing the street.
