There are many independent laptop PC manufacturers in Japan. Panasonic Let's Note (cf. http://panasonic.jp/pc/ ) is known to have excellent battery life while being decent. Laptops from Mouse Computer (cf. http://www.mouse-jp.co.jp/ ) have almost no pre-installed crap. Unfortunately, many of them don't sell outside the country. They're probably too small/thin to Western people. People tend to think a 17-inch laptop "giant" here.
