Infoseek Japan K.K. and Lycos Japan Inc. will unite their Web portals into the one now run by Infoseek Japan on Sept. 1 to make it more competitive with Yahoo Japan Corp.

The integration is designed to provide a wider range of content on a single portal to make it more convenient for site visitors, the companies said in a statement.

The integration will be carried out with a transfer of services unique to Lycos Japan to the portal site of Infoseek Japan, they said.

Infoseek Japan and Lycos Japan are under the umbrella of Rakuten Inc., Japan's biggest Internet shopping mall operator.

Rakuten President Hiroshi Mikitani said last month he was considering integrating the management of Lycos Japan and Infoseek Japan by the end of this year. But he said he would not unify the portal sites, at least for the time being, because different categories of Web surfers have used them.
