Kamen Rider W

Kamen Rider W (仮面ライダーＷ（ダブル）) is a 2009-2010 Japanese tokusatsu drama, the eleventh series in the Heisei period run of the Kamen Rider Series. It premiered following the finale of Kamen Rider Decade on September 6, 2009, and aired alongside Samurai Sentai Shinkenger in TV Asahi's Super Hero Time programming block. Following Shinkenger's finale, it aired alongside Tensou Sentai Goseiger, until W concluded on August 29, 2010. The series is described as the "Heisei Kamen Rider 10th Anniversary Project: Fall Campaign" (平成仮面ライダー10周年プロジェクト 秋の陣). The catchphrases for the series are "We are the two-in-one Kamen Rider" (俺たちは/僕たちは、二人で一人の仮面ライダーさ) and "This clinches it!" (これで決まりだ!).

Promotion
Advertisements throughout the months of May, June, and July 2009 built up to the debut of Kamen Rider W, who first appeared at the 10th Anniversary Project MASKED RIDER LIVE & SHOW event, and also featured in Kamen Rider Decade: All Riders vs. Dai-Shocker.

Hiroshi Tanahashi of New Japan Pro Wrestling is a self-admitted fan of Kamen Rider W, and in June 2010 made a new costume designed after Kamen Rider Double FangJoker's design and wore it to a match in Osaka on June 19. Rin Asuka also appeared at the match to promote the show.

Production and casting
The series' main writer is Riku Sanjo and the main director is Ryuta Tasaki. The theme song titled "W-B-X ~W-Boiled Extreme~" is performed by Aya Kamiki with former JUDY AND MARY guitarist TAKUYA as the unit "Aya Kamiki w TAKUYA" (上木彩矢 w TAKUYA). The creature designer is Katsuya Terada, previously the character designer for Blood: The Last Vampire, the designer of Monster X for Godzilla: Final Wars, the designer of Cutie Honey's costume for Cutie Honey, and the mechanic and character design refinement for Yatterman.

Newcomer Masaki Suda portrays the mysterious Philip. Drama actor Renn Kiriyama, who made his acting debut as Bunta Marui in Musical Prince of Tennis: Absolute King Rikkai feat. Rokkaku ~ First Service, joins the cast as Shotaro Hidari. Hikaru Yamamoto, who made her acting debut in Watashitachi no Kyōkasho as Chiharu Nobue, portrays the female lead Akiko Narumi. Comedian and actor Takeshi Nadagi portrays Mikio Jinno and veteran actor Minori Terada, known for his leading role in The Human Bullet, portrays Ryubee Sonozaki.

Story
In the ecologically-minded city of Futo (風都), there are many windmills and the people live in harmony. However, the Sonozaki Family sell mysterious devices resembling USB flash drives called Gaia Memories to criminals and other interested parties who use them to become monsters called Dopants, committing crimes with the police force powerless to stop them. To make matters worse, the Gaia Memories carry a dangerous toxin that cause their users to go insane to the point where they could die from the life-threatening devices. After the death of his boss, the self-proclaimed hardboiled (actually half-boiled) detective Shotaro Hidari works with the mysterious Philip, who possesses the true Gaia Memory, to investigate crimes which involve Dopants. Using their own Gaia Memories, Shotaro and Philip use the Double Driver belts to transform and combine into Kamen Rider Double to fight the Dopant menace and keep Futo safe. While joined in their fight by investigator Ryu Terui, who transforms into Kamen Rider Accel, the mystery of Philip's past, his relation to the Sonozaki Family, and their Museum organization are revealed.

Wind Wave Internet radio
To tie into the show, TV Asahi, Toei, and Avex Trax have produced the Wind Wave FM Internet radio station. Only one of the shows, Wakana's Healing Princess (園咲若菜のヒーリングプリンセス), also exists within the fiction of Kamen Rider W. The other programs, DJ Hurry Kenn's FU-TO Hit on Groove music show and Tsuyoshi and Ayano's Head Wind: One-Game Match!! (向い風 一本勝負!!) show, treat the television series as fiction, explicitly referring to the songs they play as theme songs (as part of a mail in request, DJ Hurry Kenn played AAA DEN-O form's "Climax Jump", and referred to it as the theme song for Kamen Rider Den-O). All of Double's theme songs have been played as part of the various radio shows, several of which were first heard on the "radio" before being utilized as part of an episode's soundtrack. On March 7, a new radio show featuring Queen & Elizabeth titled Queen & Elizabeth's White Hearts!! (QueenとElizabethの白抜きハートマーク!!) began "airing", but was discontinued a month later. To mirror the current events in the show's story, Healing Princess was cancelled on June 13, 2010.

Kamen Rider Double, voiced by Kiriyama and Suda, made his debut appearance in Kamen Rider Decade's first film Kamen Rider Decade: All Riders vs. Dai-Shocker.

Parodies
Episode 295-A of Sgt. Frog titled "Keroro, The Two of Us are One Kerororm" (ケロロ 二人が一人ケロロ〜ム! であります) features the members of the Keroro Platoon finding an artifact that allows two of them to combine into a single Keroro, each with new powers. The episode title is based on Kamen Rider W's catchphrase and the resultant transformation resembles that of Kamen Rider Double (the characters appear to be split down the middle, with one side being, for example, Keroro and the other Tamama).
