| You need to accept other forms of romanization, or at least go by the ones provided by the jimusho's official site. 大野智 is romanized as Ohno Satoshi according to official sources, for example.
List of Errors By Group Name:
Johnny's - Iino Osami with two "i"s, not an "L". "Nakatani" Ryou, not Makatani. Oh, and there's a " 's" in the group name.
The Good-Bye - Soga Yasuhisa, not Yashisa. birthdays: Kaga - 1958/02/28, Nomura - 1964/10/26, Soga - 1963/01/07, Etou - 1963/06/08
Hikaru Genji - Morohoshi Kazumi, not Mohoroshi.
Otokogumi - Narita - 1968/08/01, Takahashi - 1969/05/20
Ninja - Yanagi - 1967/03/07, Endou - 1969/04/20, Masaki - 1969/05/29, Takagi 0 1970/03/11
Arashi - Nino's birthday is in June, not July.
NEWS - The group name *was* NewS but has since changed to NEWS, so be careful with that.
Hey! Say! JUMP - it's "Inoo Kei," not "Inou Kei," 伊野尾 is pronounced "いのお/Inoo," so that's not even a different romanization, just a pure error. His birthday is wrong too, he was born in June, not July. Okamoto Keito was born in 1993, not 1983.
Nice quiz overall though, I really liked how you included all of the groups in the history of the jimusho and not just the current ones. |
