is Rimi Natsukawa's sixth original album, released on . The album was a 2-CD set, with the first CD featuring studio recordings, and the second performances from her tour. The limited edition also featured a DVD.
Umui Kaji was released after two singles. "Sayà Ânara Arigatà  (Ama no Kaze)/Mirai" in August 2006 was a re-arrangement of her song "Sayà Ânara Arigatà Â" (a single from Ayakaji no Ne) by the song's writer, Kentarà  Kobuchi of Kobukuro. The second A-side, "Mirai," did not feature on the album. "Furusato" was written by singer Noriyuki Makihara, and was used as the theme song for the drama Asakusa Fukumaru Ryokan.
The studio disc features a greater variety of songwriters/arrangers than Natsukawa's previous works. "Unju no Furusato" was a collaboration between Chiharu Tamashiro of the band Kiroro and entertainer Gorie (who wrote the song's lyrics). It was used as the movie "Minami no Shima no Furimun"'s theme song (which starred Gorie). The bonus track, "MÃÂmÃÂhà Â," is a cover of the song sung by Josephine Siao in the 1960 Chinese film Ku Er Liu Lang Ji (è¦å ÂæµÂ浪è¨Â). The original version features on "Famureuta."
The live disc was recorded at Natsukawa's Uta Sagashi no Tabi concert at the Chukyo University Culture Meeting Hall (ä¸Â京大妿ÂÂÃ¥ÂÂå¸Âæ°Âä¼Â館) on December 23, 2008. Two exceptions are "Amazing Grace" and "Toki no Wakare ni Mi o Makase," which were recorded at the Machida town hall (çºç°å¸Âæ°ÂãÂÂã¼ã«) on October the 24th, 2008.
The entire live disc is made up of cover songs. Tracks #1-#4 (as well as #9) are songs that did not make it onto the ' in 2007. Tracks #5-#8 are covers already released by Natsukawa (three tracks are from 2002's Minamikaze, and one from 2003's Sora no Keshiki)
The limited edition DVD features recordings from the December concert.
