Why you should experience Otemachi One Garden in Tokyo, Japan.
Otemachi One Garden is an expansive contemporary landscape where Otemachi's corporate scale, palace-edge greenery, open lawn and carefully structured planting create an unexpected outdoor interval within Tokyo's principal business district.
Set along Uchibori-dori near Hibiya-dori and just steps from the Imperial Palace moat, the garden unfolds across broad lawns, planted terraces, shaded paths and waterside elements at the western edge of the Otemachi One complex. Low planting preserves long views toward the palace canopy before denser groups of trees create smaller areas for sitting and walking beneath the surrounding towers. Changes in planting height and ground level give the landscape several distinct spatial conditions without interrupting its openness toward the palace. The result is a garden whose unusually generous dimensions turn the edge between Otemachi and the Imperial Palace into a destination in its own right.
What you should know about Otemachi One Garden.
Otemachi One Garden is best known for completing the Otemachi One redevelopment with approximately 6,000 square meters of green space designed to extend the enormous vegetated edge of the Imperial Palace into Otemachi. Mitsui & Co. and Mitsui Fudosan developed the garden as the final phase of the approximately 358,700-square-meter Otemachi One project, whose principal buildings had been completed on February 23, 2020. Landscape studio office ma led the landscape design, with Nikken Sekkei and Kajima Corporation forming the design consortium and Kajima executing construction. Garden construction reached completion in December 2022, and the public opening followed on December 16, formally completing the integrated development. Approximately 3,000 square meters of the site are organized principally around an event-capable lawn, giving half of the garden substantial uninterrupted open ground within the dense office district. Seven zones divide the broader landscape into different forms of outdoor occupation, including lawn, tree shade and areas associated with dining and work. The 6,000-square-meter footprint, office ma landscape scheme, seven-zone organization and 3,000-square-meter lawn established a substantial new public landscape along one of Central Tokyo's most intensively developed commercial districts.
Planting strategy gives that acreage an environmental function extending beyond the creation of open ground. Approximately 300 medium and tall trees and 6,600 shrubs were introduced across the garden, with the larger planting mass intended to suppress increases in ground-surface temperature and create a cooler zone within Central Tokyo. Regional native trees had already been specified in the development plan by 2019, connecting the planting strategy with biodiversity objectives and the formation of a broader urban green network. Water features add another landscape component to the planted ground, and Uchihara Creative Lighting Design developed the exterior and landscape lighting as part of its wider commission across Otemachi One. The opening program demonstrated another planned function when Winter Bloom brought floral artist Nicolai Bergmann into the garden for a live performance and specially commissioned flower display during December 2022. The native planting strategy, 6,900 trees and shrubs, water elements, environmental cooling objective and dedicated lighting program give office ma's landscape measurable ecological and civic functions within the surrounding office district.
How to fold Otemachi One Garden into your trip.
Otemachi One Garden works as the anchor for a daytime progression through Heian rebellion, Tokugawa castle administration and the institutional architecture of Japan's modern industrial economy across the immediate Otemachi and Marunouchi district.
Begin at Masakado's Tomb, where the memory of tenth-century warrior Taira no Masakado survives within the modern business district after his rebellion seized provincial government offices across the Kanto region and ended with his death in Shimosa in 940. Tradition places Masakado's severed head at the Otemachi site after its exhibition in Heian-kyo, and later memorial rites transformed the mound into a persistent place of veneration that survived the replacement of its Edo-period surroundings by government offices and corporate towers. Continue to Ote-mon Gate, the principal entrance through which daimyo entered Edo Castle for attendance upon the Tokugawa shogunate, where a Koraimon leads into an enclosed masugata before movement turns toward the larger Watari-yaguramon. The defensive arrangement converted political hierarchy into architecture by forcing approaching retinues through successive controlled spaces, and the surviving Koraimon dates to reconstruction undertaken after the Great Fire of Meireki destroyed the earlier gate complex in 1657. Conclude at The Industry Club of Japan, completed in 1920 as a reinforced-concrete and partly steel-framed headquarters for an organization created to strengthen relationships among the country's industrial leaders. Kitaro Matsui participated in the design of the five-story Secession-style building, whose Doric entrance accommodated state guests and whose rooftop sculptures by Uichiro Ogura depict figures holding a hammer and spool, architectural symbols of coal and spinning as major industries of the period. The progression moves from Taira no Masakado's tenth-century challenge to imperial authority through the Tokugawa shogunate's architectural regulation of daimyo at Ote-mon Gate into the Industry Club's institutionalization of modern industrial leadership, revealing successive systems of political and economic power embedded around Otemachi One Garden.
