A group of lawmakers will arrive in Kenya on Sunday for a two-day inspection tour that is likely to end up endorsing a controversial hydroelectric dam project.

After official meetings next week with Kenyan leaders who openly support the dam, observers say the team will probably recommend pouring an additional 10.6 billion yen in taxpayers' money into the project.

The Japan-sponsored project has drawn accusations of pork-barreling that benefits Japanese firms and lawmakers at the expense of the environment, human rights and Japanese taxpayers.
