As you know, a word order of English sentence is "Subject + verb + object", however, the order of Japanese sentence is "Subject + object + verb" and the subject is often omitted. This is kind of a big difference and confusing. For example, EN: I like dogs. JP: watashi wa inu ga suki desu. (watashi=I, inu=dog(s), suki=like) EN: I read a book yesterday. JP: kinou hon wo yonda. (kinou=yesterday, hon=book, yonda=read(past))
