"Passenger" is the third full-length album released by the band Nico Touches the Walls in Japan on April 6, 2011, through Ki/oon Records.

During the band’s split tour with "Flumpool", vocalist Mitsumura Tatsuya revealed the meaning of the name "Passenger" for the album: Although the title "PASSENGER" can, naturally, be translated as both "traveler" and "someone aboard some method of transportation" (in Japanese), we intend to do it our way.

"Diver" single was released on January 12, 2011, previously featured as the eighth opening for the anime Naruto: Shippuden months before.

Although a number of singles smaller than their previous albums, two promotional songs from "Passenger" were released: "Mosou taiin A" and "Matryoshka", chosen to be the opening for the anime C, aired in April 2011, by Fuji TV.

The tour began on April 13, in Chiba, counting twelve concerts at announcement time, added a few extra performances later.
