Does anyone have experience listing a commercial site on Japanese search engines? 
Yahoo is the most popular one over there, Google is second.
I know we need Japanese keywords, but that is no problem as our site is bilingual.
What are some good ways to increase traffic there as well?
Thank you to everyone for advice about how to get listed on search engines and increase traffic, we are working on that now.

Thank you,
Kevin Sawatzky
