Ishigaki Wall & Accessible Pathway

The Seattle Japanese Garden is undergoing a rare, historic improvement project. The $2.8 million investment will replace the Garden’s deteriorating stone wall and add an accessible looped walkway so that more people—using wheelchairs, strollers, or walkers—can safely experience the beauty of the renewed shoreline. 

The Garden will be closed June 22 - July 26, 2026, for demolition, and will partially reopen mid-summer for visitors to see our progress. 

Upon reopening July 28, construction will enter a new phase with 15th generation master stone mason Suminori Awata leading a team of artisans from Japan and America in the laborious task of building the wall stone-by-stone. Guests are invited to visit the Garden throughout the summer months to witness this unique process as the wall takes shape.

We extend deep gratitude to donors who invested in this important project.

Visiting the Garden While Work Is Underway

The Garden will be partially open during construction for visitors wishing to enjoy part of the Garden or track our progress. While we’re very excited to improve the Garden with a new wall and accessible pathway, we understand that closures are inconvenient and construction can be disruptive. Visitors looking for a quiet, contemplative Japanese garden experience may find refuge in the southern portions of the Garden, and we expect noise from the construction that will impact your visit.

About the Project

For more than six decades, the Seattle Japanese Garden has been cared for through meticulous pruning, stonework, weeding and sweeping through seasonal change—what we call the art of maintenance. This work is never finished; each generation inherits the responsibility to renew the Garden while honoring its original design and spirit.

We invite you to witness our commitment to stewardship in action this summer as the Ishigaki Wall & Accessible Pathway project unfolds. Stonemasons from Japan, teamed with American artisans, will rebuild our deteriorating North Wall, preserving both the Garden’s landscape and a rare craft that has been handed down over centuries. At the same time, we are reshaping paths so that more people—using wheelchairs, strollers, or walkers—can safely experience the beauty of the renewed shoreline.

As a crucial part of this project, the nearby walkways will be re-graded and built to be accessible, allowing the Garden to become even more inclusive and restorative to the 100,000 guests visiting annually from our local communities and across the globe.

FAQ:

  • The Seattle Japanese Garden will be closed June 22 - July 27 for Phase 1 of our ishigaki wall & Accessible Pathway project — a $2.8 million improvement to replace the Garden’s deteriorating retaining wall and add an accessible looped walkway at the north end of the pond.

    The ishigaki (stone walls) will be built by Suminori Awata, one of the last remaining stonemasons of a 15-generation lineage specializing in traditional Japanese dry-stone walls—built without mortar—designed for stability, durability, and earthquake resilience in castle foundations, temples, and gardens. These walls stand for centuries. The accessible pathway will allow wheelchair users and stroller-pushing families to enjoy the shoreline area for the first time. 

  • There will be a full closure for five weeks from June 22–July 27, followed by a return to our regular hours 6-days-a-week through mid-October (we are closed on Mondays). Upon reopening July 28, construction will enter a new phase with 15th generation master stone mason Suminori Awata leading a team of artisans from Japan and America in the laborious task of building the wall stone-by-stone.


    From late-July through mid-October, the Garden will be about 80% open, with construction closures for the ishigaki construction at the north end of the garden. Once completed in mid-October, the Garden will fully reopen for visitors to enjoy the new space through December 1, when we close for the season. Guests are invited to visit the Garden throughout the summer months to witness this unique process as the wall takes shape. We will continue to update this webpage with the most current schedule.

  • Due to the nature of this work, the project is only possible in the summer. While we’re closed, we will also be completing deferred maintenance on our walkways and the dobashi bridge.

  • Yes, you can still visit for most of the summer. Except for the June 22–July 27 full closure, the Garden will be open. The most up to date schedule will be reflected on this page (above) and on our Hours & Operations page.

  • This project is made possible through a strong partnership and the generosity of lead supporters. We extend our heartfelt thanks to the donors whose leadership gifts are bringing this project to life: 

    Aldarra Foundation ♦ Steve & Peggy Garber ♦ Bill & Virginia Goldberg ♦ Japanese Garden Society ♦ The Norcliffe Foundation ♦ Doug & Noriko Palmer ♦ Suzanne Ragen ♦ Steve Alley & Amy Scott ♦ Patti & Michael Brawer ♦ Larry Hubbell & Shelley Butler ♦ Gail & Ron Irving ♦ Susie Marglin ♦ Keiko Minami ♦ Maribeth O’Connor & Chuck Nordhoff ♦ Cam & Tori Ragen ♦ John Reed & Karen Overstreet

  • We look forward to offering continued programming at the Seattle Japanese Garden. Learn more on our Events page.

  • For guests seeking a Japanese Garden experience, we recommend visiting our friends at Kubota Garden in south Seattle or Seike Japanese Garden in neighboring SeaTac, Washington.

    For guests looking for a beautiful place to stroll, the Washington Park Arboretum is a 238-acre public park surrounding the Seattle Japanese Garden, complete with accessible pathways and numerous gardens.

  • Financial donations to the Seattle Japanese Garden supports the quiet devotion of the gardeners, artisans, and Chado practitioners who prune, set stones, mend bamboo fences, or prepare the tea house to receive guests. At the Garden, maintenance isn’t mere upkeep; it’s how cultural knowledge is passed from mentor to apprentice. Your gift helps sustain ongoing mentorship and essential materials for the next year—and for the generation of Garden stewards to come. Make a gift.
