Zoho is a suite of office software that you can use online, or you can download onto your computer and use offline, and then synch with your online content. So you get the best of both worlds. Speaking of both worlds, you can get Zoho in Japanese too. With about 20 diffferent applications (word processing, spreadsheet, presentation, database, email, planner, chat wiki, notebook), you can’t go wrong. Especially since it’s all free.
