DoCoMo just announced that their users will be able to do keyword searches from the top page of the Japanese i-mode menu for easier access to official i-mode sites. In addition, the search results page will provide links to nine search engines so users can view non-official i-mode sites and other websites with the same keyword. The new service will be offered from October. No special set-up is required, and the search box will be automatically displayed from the service launch according to the statement.
Please see the .PDF attachment for the list of available search engines.
