Do it in the same way like SEO for any other local website. Try to get as many links from Japanese websites as possible.
first of all, japanese google isnt any different from other countries google. so thats why you should work on your regular likbulding techniques. only specified for japanese site links
A good place to start is at home: <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="[B][COLOR="Red"]en[/COLOR][/B]" lang="[B][COLOR="Red"]en[/COLOR][/B]"> Code (markup): Replace the red "en" text with whatever the short name for Japan is.
find someone to write in Japanese characters if you can do that then its the same as any other country domain
should i use a webhosting based in japan? where can i find japanese directory submission list? where can i find japanese article submission list? ~~~ online translation software is not good enough to help me find these resources!!
It's the same like in Google com or Google co.uk. There are no differences between Japanese or UK Google, just pay more attention on exchanging links with Japanese sites and submitting at Japanese directories and so on.
Host ur website on a server located in japan, get a .jp domain and get backlinks from as many japanese sites as possible.. Thats all.
Yeah. Just make sure that you server is hosted in japan most of your backlinks come from jp sites. most of the traffic is from japan ip
There will be companies out there that will be able to translate in to Japanese text and also do some link building for you, you want to do a search for web copy translation services. You should be able to find a package deal at a good price.
