Where to find SQL Server 2008 Express multi-language install package

I want to find SQL Server 2008 Express multi-language install package, e.g. Japanes version installation package, Chinese version installation package, Korean version installation package. But from http://www.microsoft.com/express/sql/download/, I cannot find a standalone install package. I can only find a install package with Microsoft Web Platform Installer, the installer will access internet to download and then install SQL Server 2008 Express.

I need to find a standalone multi-language install package so that I just need to download once from internet and can copy to other machines which do no need to access internet. Where to find a standalone install package which could be used without internet environment?

thanks in advance,
George
