Nipponster can be really good for specific searches, like:

what is the best ramen in Tokyo?

How can I get Japanese goods shipped to me?
Etc.

Let me explain why.
Nipponster, in addition to filtering results, weights results higher from a number of Japan-related forums.

So it is like searching the forums at japanforum, jref, japan-guide, etc. ALL AT ONCE.

Try out your search and then comment here on what you find. Good bad or ugly we LOOOVE feedback.
