Answer by taking a quote from the following article:

Ryuichi Sakamoto (Ban Ben Long Yi , Sakamoto Ryuichi, born January 17, 1952) (Japanese pronunciation: [sakamoto rjW:itci]) is a Japanese musician, singer, composer, record producer, activist, writer, actor and dancer, based in Tokyo and New York. He began his career while at university in the 1970s, as a session musician, producer, and arranger.

Sakamoto's production credits represent a prolific career in this role. In 1983, he produced Mari Iijima's debut album Rose, the same year that the Yellow Magic Orchestra was disbanded. Sakamoto subsequently worked with artists such as Thomas Dolby; Aztec Camera, on the Dreamland (1993) album; and Imai Miki, co-producing her 1994 album A Place In The Sun. Roddy Frame, who worked with Sakamoto as a member of Aztec Camera, explained in a 1993 interview preceding the release of Dreamland that he had had to wait a lengthy period of time before he was able to work with Sakamoto, who wrote two soundtracks, a solo album and the music for the opening ceremony at the Barcelona Olympics, prior to working with Frame over four weeks in a New York studio. Frame said that he was impressed by the work of YMO and the Merry Christmas Mr Lawrence soundtrack, explaining: "That's where you realise that the atmosphere around his compositions is actually in the writing - it's got nothing to do with synthesisers." Frame's decision to ask Sakamoto was finalized after he saw his performance at the Japan Festival that was held in London, United Kingdom. Of his experience recording with Sakamoto, Frame said: He's got this reputation as a boffin, a professor of music who sits in front of a computer screen. But he's more intuitive than that, and he's always trying to corrupt what he knows. Halfway through the day in the studio, he will stop and play some hip hop or some house for 10 minutes, and then go back to what he was doing. He's always trying to trip himself up like that, and to discover new things. Just before we worked together he'd been out in Borneo, I think, with a DAT machine, looking for new sounds.
