Marriott's English hotel addresses look like this:
http://www.marriott.com/hotels/travel/CODE-hotel-name/

And those in Chinese and Japanese look like this:
http://www.marriott.com.cn/Channels/...age/CHINA/CODE
http://www.marriott.co.jp/Channels/g...age/JAPAN/CODE

So just browse to the English site, copy down the code (eg. "BJSCY" for Beijing Courtyard), plug it into the Chinese/Japanese address (use all caps), and Mao's your uncle.
