Seattle's Japanese Garden is about to swap its usual calm for construction clatter, shutting its gates for a multi week, multi million dollar overhaul right as the city gears up for World Cup visitors. The full closure runs from June 22 through July 27 while crews take apart a failing north stone wall and prep the site for a new accessible looped walkway. The garden is slated to partially reopen on July 28, even as stonemasons keep rebuilding the wall, with a 15th generation Japanese master stonemason working alongside American artisans.
What the project will change
The Ishigaki Wall & Accessible Pathway project will replace the garden's deteriorating retaining wall and reshape shoreline paths into a looped route that is friendly to wheelchairs and strollers. According to the Seattle Japanese Garden, the garden will be fully closed June 22 to July 27 while the old wall is demolished and removed. Visitors will be allowed back starting July 28, but only for a partial reopening as crews begin the stone by stone reconstruction at the north end. The garden is warning that construction noise and restricted access in that area will affect visits through the summer and into the fall.
Timeline, schedule and budget
Seattle Parks and the Arboretum Foundation report that construction on the north wall is scheduled to run from June through November 2026, with the most disruptive demolition work packed into this summer's closure window. The project cost is listed at roughly $2.8 million on the garden's site, while the Arboretum Foundation notes that $2.3 million had been raised as of April 2026, leaving about $106,000 still to go. Project partners say additional work, including paving and a planned pavilion, is expected to continue into the fall after the stonework on the wall is complete.
Craftsmanship and preservation
Organizers are leaning hard into tradition for the rebuild. The wall will go back up using classic ishigaki dry stone techniques, overseen by 15th generation master stonemason Suminori Awata and a team from Japan and the United States. As the Arboretum Foundation describes it, Awata "listens to the stones and puts them where they want to go," a meticulous, hand carved approach that organizers say is intended to give the new wall durability measured in decades, if not a full century.
Why it is scheduled for mid summer
Garden leaders say the sheer size and weight of the work, including moving large granite boulders and regrading shore paths, makes summer the only realistic season to take on this restoration. The timing overlaps with Seattle's FIFA World Cup summer, but city guidance on a construction pause specifically carves out an exception for public spaces managed by Seattle Parks, so the garden project is allowed to move forward. The pause is aimed at keeping streets and sidewalks clear for the influx of visitors, not at halting work inside park grounds.
Visitor tips
Anyone eyeing a mid summer visit should plan around a full closure from June 22 through July 27, followed by limited access after July 28 as work continues at the north end of the garden. The project page will carry the latest on hours and any schedule tweaks. For a quieter alternative while the machinery is running, the garden suggests nearby Kubota Garden or Seike Japanese Garden. Local coverage from FOX 13 Seattle also breaks down the project timeline. For updates and FAQs, see the project page on the Seattle Japanese Garden website.
