本项目是洋马（YANMAR）东京分公司的重建计划，位于日本代表性枢纽车站东京站的东面。东京站东侧的八重洲商务区可以追溯到江户时代，曾是河运发达的街区。即使在今天，在正在开展多个大型再开发项目的日本国内，这里也是最具潜力的地区，每天人来人往络绎不绝。这座连接城市与车站的建筑，是在全球开展“食品生产”和“能源转换”技术的企业洋马的品牌基地，采用了符合其东京站前门面定位的外观设计和内部环境设计。

The reconstruction plan for the Yanmar Tokyo office on the east side of Tokyo Station, one of Japan’s most iconic train terminals. Yaesu, the business district to the east of the station, was a center for logistics by canal in the Edo era. Today, it has become a popular district with some of the best development potential in the country, with several major redevelopment projects taking root. The building bridges Tokyo Station and the Yaesu area and acts as a branding hub for Yanmar, a company that develops technology for “food production” and “energy conversion” worldwide. Its exterior and interior environment is designed to make it a suitable face for the company in this station-front location.

“出航世界”的外观设计

面向东京站繁华街道的建筑外装上覆满了管状百叶。由管状百叶制作而成的外立面从地面到低层部分采用船头形状，顶部采用帆的形状，整体上形成一艘船的造形。设计强调从地块到十字路口的轴线，以地处路口处独有的转角设计为目标，致力于以强有力的形态最大程度地呈现出纯粹性、象征性和独立性。

The street-facing façade toward Tokyo Station is clad in pipe louvers. On the ground level and below, the façade’s form mimics the bow of a ship, and above, a sail. We aimed for a strong form that prioritizes purity, symbolism, and autonomy, with an awareness of the axis between the site and the adjacent intersection.

独特的外观设计除了体现八重洲这一江户城下运河所在地的区位特性外，还通过外观“船”的造型让人联想到洋马的业务领域“大海”，这一贴合八重洲区位特性且符合洋马客户特质的外观设计向全世界散播着品牌影响力。

The design was made possible by the corner condition of the site, and speaks to both the situation of the building and the client company. Inspired by Yaseu’s history as the location of the former canal beneath the Edo Castle, as well as Yanmar’s work in the maritime field, this iconic ship-like design makes a statement toward the world.

作为品牌传播基地的公共空间

南面外墙采用了面积约800平方米的大型管状百叶绿化系统。无论是电梯间、卫生间，还是休息区，在办公楼层共用部分的任何位置都可以感受到室外的盎然绿意。从南面相邻的大楼也可以看到一整面被绿植覆盖的墙面，为人们提供了可切身感受大自然的环境。

On the south exterior wall is a large-scale pipe louver greening system covering approximately 800 m². The greenery can be perceived from anywhere in the common areas of the office floor, such as the elevator hall, restrooms, and refreshment corners. The green wall can also be seen from the neighboring building to the south, and provides a natural environment within the city.

在低层部分的3层挑空处，通过水耕栽培进行百叶绿化。昼夜节律LED照明兼具培育植物和营造整个挑空空间效果的功能，一天中色温也随时间在不停变化。设计师致力于打造一处东京站周边罕见的亲生命性设计的公共空间，希望这里能成为日常生活中任何人都可以自由停留的地方，前往周边大楼和东京站的人们不禁想要驻足片刻的地方。

In the three-story atrium on the lower level, louvered greenery is grown using hydroponics. Circadian LED lighting serves both as a plant growing device and as a spatial effect for the entire atrium, and changes color temperature from moment to moment throughout the day. This is a biophilic public space, rare in the vicinity of Tokyo Station, where anyone can come and go freely, and where those on the go might want to stop and linger.

此外，绿化挑空空间和外墙上的大型绿化一起表现着洋马的另一个业务领域“大地”。装饰材料采用了适合表现大地的天然材料，比如地面的木质地板和天花板的木质百叶等。

The green atrium space, together with the large-scale greening of the exterior walls, is an expression of Yanmar’s work with the earth. Natural materials in the finishes, such as wood flooring and louvers on the ceiling, also represent this element.

重视日本大米种植的洋马在1层策划了一个以大米为主题的画廊，2层则是以大米和农业为主题的餐厅。通过挑空将地下1层到2、3层的繁华串连到了一起，挑空空间本身就是洋马的品牌传播内容。

The building also features spaces born from Yanmar’s recognition of the great importance of rice farming in Japan. On the first floor is a gallery, and on the second floor is a restaurant that highlights rice and agriculture. The atrium creates a continuous bustling atmosphere from the basement to the second floor, and the space itself serves as a piece of content that communicates the Yanmar brand.

对于在该建筑内办公的人们来说，不仅能在眺望挑空空间的同时前往B1层入口和电梯间，还可以在感受各种人群活动和灯光效果带来的时间变化的同时进出办公室。如此一来，这个作为办公入口空间的公共空间就成为该建筑的一大特色，展现着东京站前写字楼应有的卓越风姿。

The entrance and elevator hall on the B1 floor offer a view of this atrium space, where the various activities and light effects over time can be felt by employees as they enter and leave the office. This public space is a major feature in the approach of this building, and sets the standard for office buildings in front of Tokyo Station.

环保先进企业的生动展示空间

该建筑的机器设备均采用节能高效的洋马产品，对客户而言这里就是一个无比生动的展厅。内燃发电机的热电联产系统和使用高效燃气热泵空调的辐射冷暖空调系统等，多种洋马产品的使用实现了高BCP性能和高环保性能。

Energy-saving and high-efficiency Yanmar products are used in the equipment of this building, making it a living showroom for customers. A variety of Yanmar products are incorporated—including a cogeneration system using gas engine generators and a radiant heating and cooling system using high-efficiency gas heat pump air conditioners—to achieve high BCP and environmental performance.

此外，建筑还在防灾、环保和居住舒适性方面采用了许多最新技术，如以办公楼层为对象的中间层隔震结构、使用B1层公共广场作为灾害时回家困难人群的临时避难场所、墙面太阳能发电板、风力发电、使用多孔天花板的辐射兼用型自然通风系统等。

In addition, the building incorporates the latest technologies for disaster prevention, environment, and living comfort, such as a mid-story seismic isolation structure for the office floors, a public plaza on the B1 floor to provide a temporary evacuation site for people who cannot return home, wall solar panels, wind power generation, and a natural ventilation system that uses radiation in combination with a perforated panel ceiling.
