TOKYO, Oct 28 (Reuters) - Japan and the United States

are preparing a fact sheet on potential investment projects in

the U.S., involving Japanese firms such as Mitsubishi Heavy

Industries ( MHVYF ), a senior Japanese government official said.

The potential projects are a part of the $550 billion (83

trillion yen) investment package agreed under Tokyo's tariff

deal with Washington in September, according to the source.

The fact sheet will include power generation and

automobile-related products as potential investment projects,

the source said.

The U.S. is particularly interested in a power generation

project involving Mitsubishi Heavy Industries ( MHVYF ), and the first

project could be selected as early as this year after carefully

examining other projects, according to the source.

"We have yet to develop specific projects, but at this point

we will present the names of companies and projects that are

interested in investing in the U.S.," said the source.

The fact sheet is expected to be released after being

finalised by Prime Minister Sanae Takaichi, President Donald

Trump and working-level officials from both countries, the

source said.

The Japanese government and the U.S. embassy in Japan were

not immediately available for comment. A spokesperson for

Mitsubishi Heavy Industries ( MHVYF ) declined to comment.
