Content translation links work, Language switcher doesn't

greetings,

I've successfully been able to translate my content and can toggle between languages with the content translation links. However the language switcher block doesn't change anything. When I use my language switcher on my homepage, which has translated content on it, my page will go from www.example.com to www.example/com/ja but the Japanese translations don't appear -- everything is still in English (unless I use the translation links.)

I imagine I'm missing a simple connection. Thanks in advance.
