By Kentaro Okasaka TOKYO (Reuters) -Japanese shipper Kawasaki Kisen (K-Line) is adjusting its U.S. services and is prepared to reroute more ships away to other regions as it braces for potentially higher U.

Unlike the European Union, the Japanese government has made no indication it plans to impose any kind of reciprocal tariff on the U.S.

Early trading on Wall Street was quietly mixed as markets shift their attention toward a deluge of corporate earnings reports.

By Kantaro Komiya TOKYO (Reuters) -Japanese manufacturers' business confidence improved slightly in July and is expected to strengthen further in the coming months despite ongoing concerns about U.S.

"We're anticipating a cargo surge in July as retailers stock up on goods ordered during the 90-day pause placed on tariffs and retaliatory tariffs," Port CEO Mario Cordero said.

President Donald Trump on Monday set a 25% tax on goods imported from Japan and South Korea, as well as new tariff rates on a dozen other countries.

Anxiety over U.S. tariffs has been spreading across Japan, a central bank report shows, sending a worrying signal about the corporate outlook as trade uncertainty deepens.

Japan's Nikkei ended flat due to concerns over upper house elections and uncertain trade talks with the U.S., overshadowing gains in chip-related stocks. Investors are cautious, awaiting election results and clarity on trade negotiations as the deadline approaches.
