I usually get my example sentences from tangorin.com, but I'm taking a 9 hour flight for a business trip (unfortunately not to 日本） and wanted to freewrite in Japanese on the plane. I find example sentences incredibly useful for seeing words/phrases in context, and helps with writing tremendously. Anyway. Since I wont have internet access on a plane, Is there an offline app that has the huge database of english/japanese example sentences? I do have Kotoba on my iphone, which does have the sentences but I'd rather not rely on looking things up in my phone constantly when I have a computer right in front of me. Kotoba doesn't let you search in English for the examples either. ありがとう。

The sentences on tangorin come from the tanaka corpus, don't get example sentences there. Those sentences are really unreliable and often sound very unnatural. Get sentences from a better source, for example the 和英 dictionary on dic.yahoo.co.jp

If you're not afraid to get your hands dirty with piracy, you can get loads of dictionaries in EPWING format and run on your computer with a program such as EBWin. Especially kenkyuusha waei daijiten (often called Green Godess) is amazing for example sentences.

My hands are already dirty. I'll check it out. Thanks.
