东京火炬（Tokyo Torch）再开发区被设想为照亮日本的希望之光，位于日本最大的铁路枢纽之一——东京车站的正北方向。该区域位于国家经济战略特区内，旨在加强日本的国际经济竞争力，并且成为新的金融和商业中心。建成后，这里将容纳预计于2027年完工的日本第一高楼——390米的火炬塔、常盘桥大厦、变电站大楼、水务局、东京火炬公园以及常盘桥公园。目前，规划区内四栋破旧的建筑正在被拆除，并与包括电力和水力设施在内的城市基础设施更新一起进行分阶段替换。其中，常盘桥大厦是第一个完工项目，它是一栋38层、212米高的综合体。
Located directly north of Tokyo Station, one of Japan’s largest railway hubs, the Tokyo Torch redevelopment district is envisioned as a light of hope illuminating Japan. The district sits within a National Strategic Special Zone, intended to strengthen Japan’s international economic competitiveness, and will be a new center of finance and business. It will include Torch Tower, projected to be Japan’s tallest building at 390 meters when completed in FY2027; Tokiwabashi Tower; an Electrical Substation Building; a Sewerage & Waterworks Bureau Building; Tokyo Torch Park; and Tokiwabashi Park. Four existing dilapidated buildings are being demolished and replaced in stages in conjunction with the renewal of urban infrastructure including electrical and water facilities. Tokiwabashi Tower, a 38-story, 212-meter-high mixed-use building, is the first element of the project to be completed.

常盘桥大厦矗立在东京站周围的高楼中，将成为下一代商业中心，不仅提供支持多样化工作方式和创新的优质办公空间，而且具有出色的环境和安全性能。其整体外形象征划开未来的桨叶，而上部还是包裹在阴影网格之中，符合国际金融中心的外观设计。网格遮挡阳光，如同传统日本建筑中的木格栅（kigoshi）以及推拉门上的和纸（shoji）一样，轻柔地连接室内外环境。
Soaring among the tallest mixed-use buildings around Tokyo Station, Tokiwabashi Tower is a next-generation business center offering quality office space that supports diverse work styles and innovation while providing outstanding environmental and disaster-safety performance. The building’s form suggests a blade cutting open the future, while the upper section is wrapped in a grid that creates depth and shadow—an exterior design fitting for a center of international finance. The grid blocks sunlight much like kigoshi (wooden latticework) and shoji (paper-covered sliding doors) do in traditional Japanese architecture, gently connecting the interior and exterior environments.

地下一层和地上两层是餐厅和酒吧，三层是自助餐厅，八至三十七层是办公室。二层大厅以及三、八、九层以江户城的墙壁和常盘桥的石雕为灵感，采用水磨石墙面。此外，为了提高员工的办公效率和满意程度，项目中还大量使用人们熟悉的天然材料，如长期应用于日本建筑的木材和石材。员工可以从任何办公楼层直接进入MY Shokudo餐厅、三层自助餐厅以及休息室。虽然这栋大楼主要服务于内部人员，但还设有配备厨房的活动大厅，促进社区互动并且可供邻近居民晚间使用。
The first underground floor and first two above-ground floors are occupied by restaurants and bars, the third floor is a cafeteria, and the eighth through thirty-seventh floors are offices. The terrazzo walls in the second-floor lobby and on the third, eighth, and ninth floors feature motifs inspired by the walls of Edo Castle and the stonework of Tokiwa Bridge. The abundant use of familiar natural materials such as wood and stone, long utilized in Japanese architecture, is intended to enhance productivity and satisfaction among workers. Workers can directly access MY Shokudo, the cafeteria and lounge on the third floor, from any office floor. While this facility primarily serves employees in the building, there is also an event hall with a kitchen to encourage interaction, and at night the facility can be used by people who live in the neighborhood.

将安全放在首位的结构设计
A Structural Design that Puts Safety First
常盘桥大厦的基地周围环绕着日本桥河、地下高速高速公路和变电站，是整个开发区中最小、形状最不规则的地块之一。为了确保大厦相较于其他大型写字楼更具竞争力，其上层的楼层面积必须被扩大。因此，从第八层开始，通过调整结构柱角度向外倾斜，楼层面积得到扩增。此外，阻尼器和支撑构件的合理放置确保了建筑在常发于日本的地震和台风情况下仍然保持安全。
The building site for Tokiwabashi Tower is among the smallest and most irregularly shaped lots of the entire redevelopment district, hemmed in by the Nihombashi River, a high-speed underground highway, and an electrical substation. To ensure that the tower is competitive with other large-scale office buildings, it was necessary to expand the floor plate on the upper levels. Starting on the eighth floor, floor area is expanded by angling the structural pillars to overhang the lower floors. The appropriate placement of dampers and braces ensures that the building remains safe in the event of earthquakes and typhoons, which are common in Japan.

日本文化色彩下的艺术品
Artwork In the Colors of Japanese Culture
为了支持年轻艺术家，常盘桥大厦的内部展示了18件来自艺术界前沿的艺术家的当代作品，主要来自日本和亚洲其他地区。这些作品反映了日本节日和歌舞伎剧院的明亮色彩主题，激发了游客的感官，并为建筑内部增添了活力。
To support young artists, the interior of Tokiwabashi Tower features eighteen contemporary works by artists at the cutting edge of the art world, primarily from Japan and the rest of Asia. These works, curated to reflect the vibrant color themes of Japanese festivals and kabuki theatre, thrill the senses of visitors and add excitement to the building’s interior.

东京火炬公园
TOKYO TORCH Park
再开发区（包括常盘桥大厦和未来几年将建成的建筑）的中心是一个约7000平方米的大型广场，这里可用于日常使用和特殊活动，如音乐会、体育活动和市集等。此外，广场上还展示了来自日本各地的特色产品，包括从池塘里的彩色锦鲤、地面上种植的草到景观植物，均为国际游客提供了了解东京以外的日本的机会。
At the center of the redevelopment district (including Tokiwabashi Tower and the buildings that will be completed in coming years) is a large plaza measuring about 7,000 square meters, available for both everyday use and special events such as concerts, sports, and markets. The plaza also showcases specialty products from throughout Japan, from the colored koi fish in the pond and the grass planted on the ground to the landscaping plants, providing an opportunity for international visitors to learn about the Japan beyond Tokyo.

在常盘桥大厦中，三层餐厅设有面向广场的露台，为适用疫情期间户外用餐的人提供了宜人的空间。夜晚，玻璃内饰像灯笼一样漂浮在空中，创造出浮世绘木版画般的场景。该项目通过这种方式有意地开发建筑底层，延续了江户时代（1603-1868）的城市历史和文化，即欢迎人们工作、用餐、从外国来访和家庭出游的各种活动，为城市增添了活力。该项目的未来阶段将基于这种方式，连同水务局、变电站大楼和火炬塔一起进行建造。
Facing this plaza are Tokiwabashi Tower’s three floors of restaurants with adjoining terraces, offering a pleasant space for enjoy outdoor eating that is useful in the era of Covid-19. At night, the glassed-in interiors float like lanterns, creating a scene evocative of an ukiyoe woodblock print. By intentionally developing the base of the tower in this way, the project continues an urban history and culture dating to the Edo period (1603–1868) of welcoming a diversity of activities by people working, eating, visiting from abroad, and taking family outings, thus adding to the energy of the city. Future stages of the project will build on this foundation with the Water & Sewerage Bureau Building, the Electrical Substation Building, and the Torch Tower.
