Downbeat in Yokohama is one of the classic jazz spots in the entire Kanto (Tokyo Metropolitan) area. It first opened in 1956 and is now on its third owner, then young and friendly Yoshihisa-san who took over the joint in April 2017. (He assured me he's keeping the place as is, and even adding to the 3700+ jazz records already behind the counter.)
DB is a hardcore cafe/bar where the music comes first; the volume is loud and in your face, making conversation difficult if not impossible in the main area by the speakers on the left, though the seats on the right side by the bar counter are a bit removed and thus quieter. (The bar seats are also non-smoking) The music selections are varied; you'll hear anything from classic swing to Pharoah Sanders and all in between.
It's kind of difficult to capture in words the vibe of such a classic old Japanese jazz joint, with the faded posters and dark lighting. Check the pictures here for a taste, but be sure to visit there at least once. It's a treasure for jazz fans and a place that captures the old time port style of Yokohama.
DB is in the historical port side block neighborhood of Noge, across from the main Sakuragicho-station front plaza. Lots of little drinking dens, old karaoke pubs and some other jazz joints to visit around here if you have a night.
