The park occupies reclaimed land that was previously utilized for port-related industrial logistics.
The layout was specifically engineered to integrate with the surrounding historic Dejima architecture.
It contains a dedicated grassy 'rest zone' that covers approximately 1.5 hectares of the total park area.
The park's promenade is part of a larger waterfront redevelopment project aimed at reconnecting the city center to its harbor.
Nagasaki Seaside Park is a modern waterfront recreational area located along the harbor in the Tokiwamachi district. The park features expansive grassy lawns, paved walkways, and wide-open views of the Nagasaki Port and the Iojima area. It is a central hub for outdoor fitness, casual picnics, and community events throughout the year. The grounds are designed to prioritize accessibility with flat, barrier-free paths suitable for walking and light cycling. It frequently serves as a venue for local food festivals and seasonal maritime celebrations. The site connects directly to the Dejima Wharf area, making it a natural transition point between the historic waterfront and the modern city center.

Do not attempt to swim in the harbor, as it is a working port and prohibited.
Maintain noise levels during local events and keep the lawn free of litter.
