You may really want to understand the Japanese language. However, some of you may be stuck with Japanese sentence translation. That is okay. I have devised a few "Japanese Sentence Translation" tips to help you get through your difficult time.
Pick up a Japanese Dictionary. This will definitely help you translate the Japanese sentence. You can grab one at Amazon.com for around $15(USD). This is a pretty good investment toward easing your pain over understanding that Japanese sentence.
Get help from someone that speaks Japanese. This is even smarter than the first tip I gave you. If you know someone that can read and understand Japanese, you can simply show them the sentence you are struggling with. After, they will give you the answer and solve your problem right away. Not only that, you will get to keep your $15 that you would have spent on the dictionary. Like I said, this tip is smart!
Watch Japanese movies with English subtitles. This method will help you understand the Japanese language. You will probably run into your sentence through out the movie. Even though it may not be the best plan to help you understand a single sentence, you will probably over benefit by learning the majority of the Japanese language this way.
Use the language translation tool on Google. It can be found on the Google's main page under the hyperlink, "Language Tools" beside the search box. This can help you translate the Japanese sentence you are having trouble with instantly. Just cut and paste the sentence into the "Translate Text" box; pick the language of the sentence you want to translate in the first drop down box--i.e., Japanese; pick the language that you want the sentence to translate to--i.e., English or whatever other language preference you have; and, press the button "Translate".
Get the right tools that can properly teach you how to learn the Japanese language. This is the best Japanese sentence translation tip that I can give you. Somehow get your hands on software, books, audio courses, into a class, or go to Japan and actually learn the language. Not only will it help you now with you current translation problem, but you will have this language skill for the rest of your life!
These were a few tips that can help you with your Japanese sentence translation problems. Personally, I would focus on learning the entire language than just one sentence. There are more benefits to this: you will get bilingual jobs, you can easily travel to Japan and not suffer from the language barrier and you will feel intelligent for learning something that can be deemed difficult. Nonetheless, if the sentence is all that you are after, I hope these tips help.
