Sony Camcorder in Japan

I'm from malaysia and will be visiting japan soon. Just wondering how much is the prices of Sony Full HD Camcorder, HDD version and DVD version?

Is it cheaper in japan or Malaysia?

Does the Japan's Sony comes with international warranty?

Is the camcorder available in English version since i heard most are in japanese language?

Amazon.co.jp says DVD version is 68500 yen.

It must be a Japanese model, though.
HDD version is not listed.

Overseas models sold in Japan come with international warranty and English instructions.
