Experts have estimated the impact of the new announcement of tariffs by US President Donald Trump on the Japanese economy.

The White House said on Saturday that the president was implementing tariffs of 25 percent on imports from Canada and Mexico, and an additional 10 percent on products from China.

The Institute of Developing Economies at the Japan External Trade Organization, or JETRO, projects that the measure will push up Japan's GDP by 0.2 percent by 2027.

The institute says Japan's exports, such as auto-related shipments to the US, will increase while those from Canada, Mexico, and China are likely to drop.

Meanwhile, private think tank Daiwa Institute of Research projects that Japan's GDP in real terms will suffer a drop of up to1.4 percent in two to three years.

The projection is based on the assumption that the three countries will impose retaliatory tariffs on US goods, raising import prices in all four countries.

The institute believes that this will lead to a slowdown in the global economy.

There are concerns that the tariffs could affect businesses in Japan, as many companies have footholds in Canada, Mexico, and China.

The Japanese government has set up a team in JETRO to gather information and offer consultation to affected companies.
