Aoi Miyazaki had declined to reprise the role of Komatsu Nana. She was replaced with actress Yui Ichikawa. Ryuhei Matsuda had declined to play the role of Ren and was replaced with Nobuo Kyō. Also, Kenichi Matsuyama, who portrayed Shinichi Okazaki, had been replaced by Hongo Kanata. Even though both theme songs were released ahead ("Hitoiro" of NANA starring MIKA NAKASHIMA on November 29, 2006 and "Truth" of REIRA starring YUNA ITO on December 6, 2006), the movie could only hit the #4 spot on the Movie Charts, from its release December 9, 2006 onward, and overall had very weak and low ratings. Many fans claimed that the exchange of main cast members led to the disappointing statistics. On December 18, NANA2 made its international debut in New York City, United States. New York - Tokyo brought the main actresses Mika Nakashima and Yui Ichikawa to the limited seated IFC Cinema. The movie was well received by fans. "Nana 2" once again featured the two artists Mika Nakashima and Yuna Ito, releasing songs under the names Nana starring Mika Nakashima and Reira starring Yuna Ito, respectively. Nana, starring Mika Nakashima's new single "Hitoiro" featured Takuro of Glay as composer and Nana author Yazawa Ai as the lyricist again. It did not do as well as its predecessor "Glamorous Sky," peaking at only #5 on the Oricon charts.
