Usatei (Japanese : ウサテイ) is a popular remix of a piece of music from the Touhou series by the doujin group IOSYS[1], which along with it’s promotion flash animation became hugely popular on the japanese internet/Doujin community.

A number of remixes and parodies inspired by this song and its flash animation have been made for the song on the Japanese video sharing service Nico Nico Douga (NND).


The song’s music is based on 2 soundtracks in Touhou series : Tewi Inaba’s theme from the 9th Touhou game Phantasmagoria of Flower, titled “White Flag of Usa Shrine”, which was released at August 14th, 2005[2] and Stage 5 theme from the 8th Touhou game Imperishable Night, titled “Cinderella Cage ~ Kagome-Kagome”, which was released at August 14th, 2004.[3]

Usatei was first released on the Touhou remix album Touhou Suisuisuusuu (Touhou Gathering Green Wine Drunkenness), released by IOSYS on August 17th, 2007 at the popular comic book convention Comiket.

This song begins with two guys that are about two begin a 2-player match in the touhou game Phantasmagoria of Flower View, and one of them, Beat Mario the singer and creator of many popular Touhou remixes, is boasting about his skill and tells his friend to pick Cirno as character with a specific creepy speech of Otaku. Instead, both of them picks the character Tewi Inaba, which is considered to be a rather annoying opponent due to her special attacks.

IOSYS launched the special page for this album and released this promoting flash animation on August 1st, 2007.[4]

This flash animation was made by Kagi, also famous as the creator of other popular promoting videos for Touhou remixes : Cirno’s perfect Math class, Marisa Stole the Precious Thing and Overdrive.

The feature of this flash animation is that its visual effect is changed depending on repeating counts (3rd, 5th, 9th, 15th, 24th, 33rd, 42nd, 54th, 66th, 80th, 98th, 99th and 100th). In addition, the author said the effect of shower of words (“てゐ”, “うさ”, “( ・x・)”) got inspiration from the “bullet curtain” comments on NND where Touhou remixes by IOSYS were getting huge popularity on.[5]

This video reuploaded to NND by a user has been got over 2 million veiws.[6]


Soon after it was released, this flash animation was thrown into the whirl of Touhou fever in NND, and set to a popular subject of MADs and remixes as well as other previous works. Over 600 videos related to this song’s series have been posted to there.[7]
