Noise is one of the more unique jazz cafes still around. It opened in 1980 as the sister shop to the original Noise in Shimo-Kitazawa, sadly now closed. The location of Noise is truly a surprise, as it's on the 4th floor of the otherwise unremarkable Jorna department store right next to Machida Station. I've visited over 175 jazz establishments in Japan but this was the first one I've been to that's literally inside a department store.
Noise is also noticeably larger than the average jazz cafe, seating a comfortable 40+ customers. It's a large square room with a kitchen along the back, a long counter, and tables spread all around, with some book shelves and jazzy knick-knacks in between. (Keep a lookout for the jazz coffee can.) The jazz portraits, photos and album jackets on the wall are particularly cool, especially the Weather Report mural in the back corner.
On Saturdays and Sundays (and occasionally mid-week) there are frequent live shows starting at either lunch time or 6pm, featuring some of Tokyo's finest jazz musicians so be sure to check the schedule on their home page before dropping by. Machida doesn't always have the best reputation for nightlife but if you're nearby Noise is perfect for the first stop on a Machida area jazz joint hop. Closes at 8:30 so get there early.
