A sample of a cover song by Itou Kashitarou "Shiwa", composed by buzzG, arranged by LeftyMonsterP
Itou Kashitarou (伊東歌詞太郎, Kashitarou Itou), formerly known as weezer, is a singer-songwriter and utaite known for his strong, clear, "refreshing", and earnest-sounding voice, with a narrow, almost quavering vibrato. Although this distinct vibrato is occasionally described as being fluttery and slightly "peculiar", his voice is commonly considered to be "warm" and pleasant to listen to. He is a technically sound singer, capable of hitting notes cleanly and effortlessly as well as having a decent vocal range; he is also very good at controlling his singing volume.
His first upload was in fact not a cover, but an original VOCALOID song titled "Namida ga Koboreru Mae ni" using Hatsune Miku, after which he was given the -P honorific and dubbed FuwamokoP (ふわもこP). In addition to VOCALOID work, he posted a few acoustic and arranged covers on the side under the utaite name weezer; but though they were well-received, their view counts almost never broke the 10K mark. His cover of "Melt" , posted in early 2012, was his first breakthrough hit - shortly afterwards, he created a new account, changing his utaite name to Itou Kashitarou. He has since deleted his old account (thus halting his activity as a producer), but despite this, the videos posted on it remain viewable.
He is good friends with Amatsuki, with whom he often collaborates, and is also friends with the illustrator and mangaka Kuwahara Souta, who has illustrated some of his twitter avatars. He is a close, longtime friend of LeftyMonsterP (with whom he forms the unit Itowokashi) and often collaborates with him, including composing songs or having lives together. They have known each other since childhood, and performed together in middle school. Whenever he performs live as Itou Kashitarou, he wears a fox mask, while LeftyMonsterP wears one of several other masks.
His first entry into the utattemita category was an acoustic cover of the pillows' "Strange Chameleon", however his first cover under his present name was "Narisumashi Gengar", which currently has 198K views and 8.5K mylists. His first hit cover was "Shiwa", which currently has over 381K views and 21.5K Mylists, and is the most popular cover of that song; while his most popular solo cover to date is "Children Record", which currently has over 1 million views and 36.3K Mylists as of October 2013.
His name comes from the name of the famous Edo period samurai Itou Kashitarou (伊東甲子太郎) with the only difference being the kanji for "kashi" in each; he replaced the kanji 甲子 in the historical Itou Kashitarou's name with 歌詞, the kanji for "lyrics".
He is about 180 centimeters (approximately 5'11") tall.
