I'm looking for the japanese soundtrack of ジャックと豆の木 / Jakku to Mame no Ki / Jack and the Beanstalk from 1974.

Nevermind. Found it myself.

Download Jack and the Beanstalk Japanese UST.rar from Sendspace.com - send big files the easy way (http://www.sendspace.com/file/lcn2hi)

The Sendspace link is dead but here are good unofficial FLAC versions:
Jack and the Beanstalk Japanese UST - Download - 4shared - Ghibli Fan (http://www.4shared.com/rar/r4yYEGjx/Jack_and_the_Beanstalk_Japanes.htm)
Jack and the Beanstalk English UST - Download - 4shared - Ghibli Fan (http://www.4shared.com/rar/sjGcTM96/Jack_and_the_Beanstalk_English.html)

anyone have this?
