IP address and geo location

Japanese company ‘Cyber Area Research’ provides web service API to get location from IP address. It returns Japanese area data.

Docodoco.jp

This service is provided as free for personal & non-commercial use. For company users, it provides as pay-you-go, which is based on number of your requests.

There is a similar service which is community-based service and provided for free.

hostip.info

They provide the data as well.

If you need world wide data, hostip.info is better than docodoco.jp. But if you need Japanese data only, docodoco.jp would be better.
