EXACTLY! Plus, they're Chinese. They have kanji recognition and some similar vocabulary between the two languages, so it's like English speakers learning a romance language or German. They'll probably learn it twice as fast as an English speaker would in the same situation. It's not going to be another Coconuts Musume.
I don't find myself agreeing. Granted, some vocabulary is common between Japanese and Chinese (due to Japanese borrowing Kanji words as-is), but there's a lot that isn't and a lot that superficially looks the same but means something completely different.
Just because they happen to use the same characters doesn't mean the languages are related at all. It's often said that Chinese is actually closer to English in structure than Japanese. Japanese is only ever bundled together with Korean, which, while a fair comparison, is still a far cry from the similarities between Indo-European languages. Point is, I don't think they have any advantage or an easy start just because they're Chinese. No matter the language, learning a language is still going to require a lot of blood, sweat and tears.
I think LinLin will do OK, because she has been an Egg for a while so she has been in a 100% Japanese environment for a while. Junjun however.. if she can't speak Japanese at all yet, it'll be at least 2-3 years - even if you live in the country - before you can say anything remotely smart.
I am somewhat concerned and worried for them. If Morning Musume was only about singing songs, then it wouldn't matter because you can always memorize songs phonetically, but it's sooooooooooooo much more. Hello! Morning, talk shows (Utaban etc.), all kinds of events and radio shows..
The bottom line is.. Tsunku's got balls. Huuuuuuge cojones.
