A series of New Age/kankyō ongaku albums by Takashi Kokubo, designed primarily as soundscapes for office workers and, in one case, a sound installation. The first five volumes, released in 1992, were surtitled "都市生活者へおくる音風景" (Toshi seikatsu-sha e okuru oto fūkei, "Sound landscape for city residents".) The final five were released in 1993. All ten were reissued on June 21, 1996 as "Message from Oasis."
