Akira Sakata (坂田明) came to jazz sideways. Growing up in Kure, Hiroshima, he first heard the music on shortwave radio and Voice of America broadcasts, then got hooked through film soundtracks. He studied clarinet in high school and played alto saxophone in a jazz band at Hiroshima University, where he also trained as a marine biologist, research on the water flea genus Daphnia that earned recognition from the Japanese government and that he never fully set aside even after music took over. When he started his own label in 2004, he named it Daphnia, after the organism he'd spent years studying.

He moved to Tokyo in 1969 and joined pianist Yosuke Yamashita's trio in 1972, staying through 1979 and touring internationally as the group became one of the defining acts of Japanese free jazz. Their 1976 live recording "Montreux Afterglow," captured at the Montreux Jazz Festival with drummer Shota Koyama rounding out the group, is one of the most-traded titles from that era among reissue collectors, and it's still the release most listeners meet Sakata through first.

Once the Yamashita Trio wound down, Sakata spent the early 1980s leading a run of his own groups in quick succession, all released on or around the Better Days label that anchors much of this project's reissue-era scope. The Akira Sakata Trio cut "Counter Clockwise Trip" (1975, recorded in Munich with bassist Adelhard Roidinger and drummer Takeo Moriyama) and later "Peking" (1978) and "Pochi" (1980). The much larger Sakata Orchestra, a big band with two drummers, two bassists, and a reeds section that included a young Kazutoki Umezu, released "4 O'Clock" (1981) and "Berlin 28" (1982). The Sakata Sextet cut the two-track EP "Trauma" (1982), and a separate, harder-edged project called Wha-ha-ha put out three albums in 1981 alone before a 1983 compilation introduced the group to Western listeners via Chris Cutler's Recommended Records label in the UK. Four different lineups, four different sounds, all inside about five years.

In October 1986, bassist and producer Bill Laswell brought Sakata into two Tokyo dates with his free-jazz supergroup Last Exit, alongside guitarist Sonny Sharrock, saxophonist Peter Brötzmann, and drummer Ronald Shannon Jackson, with Herbie Hancock sitting in on piano. The recordings became "The Noise of Trouble: Live in Tokyo," and it remains the release most non-Japanese listeners first heard his name from. Sakata and Laswell kept working together for decades afterward, including the ongoing "Tokyo Rotation" concert-recording series that has continued into 2026.

In 2002, Sakata suffered a brain hemorrhage. He recovered within about three months and returned to performing, and he has kept recording ever since, deep into his eighties. His catalog from the 2000s onward leans heavily toward international free-improvisation partnerships: duo and trio work with Jim O'Rourke, the American duo Chikamorachi (drummer Chris Corsano and bassist Darin Gray), noise artist Merzbow, and the trio Arashi with Swedish bassist Johan Berthling and Norwegian drummer Paal Nilssen-Love. His most recently credited sessions are dated 2026.

Sakata's alto saxophone playing sits at the harder, freer end of Japanese jazz, shaped directly by his years inside the Yosuke Yamashita Trio's high-energy, percussive attack. He has never treated the horn as the only instrument worth using on stage: he plays clarinet and bass clarinet across his catalog and, per accounts of his live shows, will sometimes set the saxophone down entirely to make vocal sounds straight into the microphone. His bandleading across the early 1980s shows real range within that free-jazz identity, from the big-band arrangements of the Sakata Orchestra to the stripped-down two-bass, two-drum lineup of the Sakata Sextet to the more confrontational, punk-adjacent Wha-ha-ha. From the 2000s on, his work shifts further toward open, unstructured free improvisation in duo and trio settings, a natural extension of the same instincts rather than a break from them.
