2015年，日本政府选择了隈研吾（Kengo kuma）在东京竞技场设计新的国家体育场，该体育场将成为2020年东京奥运会的主场馆。
由于担心成本增加，该项目曾把建筑师扎哈·哈迪德（zaha hadid）的方案取消，用以打败伊东丰雄（toyo ito）的隈研吾构想出的设计方案。
in 2015, the japanese government chose kengo kuma to design the new national stadium in tokyo, the arena which will form the centerpiece of the city’s 2020 olympic games. the project had been controversially taken away from iraqi-british architect zaha hadid, amid concerns of increasing costs. kuma saw off competition from compatriot toyo ito, who had also presented his vision for the venue.
如今，随着奥运会的临近，designboom参观了该现场，以记录完工的体育场及其周边环境。
now, with the olympics on the horizon, designboom visited the site to document the completed stadium and its surroundings.
该体育场于2018年12月正式开放，日本首相安倍晋三，东京都知事小池百合子和隈研吾建筑师参加了颁奖仪式。在设计场地时，隈研吾希望强调环保意识。
考虑到这一点，体育场需与周围的自然环境融为一体，包括被称为明治神宫外苑的大型绿色空间。因此，建筑师将建筑设想为“立木”。
the stadium was officially opened in december 2018 with a ceremony attended by japanese prime minister shinzō abe, tokyo governor yuriko koike, and architect kengo kuma. in designing the venue, kuma wanted to place a strong emphasis on environmental awareness. with that in mind, it was important that the stadium fit in with the surrounding nature including the large green space close by known as the outer garden of the meiji jingu shrine. consequently, the architect conceived the building as a ‘living tree’.
立面由重叠的多层屋檐组成，这些屋檐取材自日本的47个县，而体育场周围已种有47,000多棵中小型树木。
据主办方介绍，无障碍座椅已分配到室内的所有楼层，这将确保轮椅使用者的可视性和舒适度。同时，自然空气会循环以帮助散热和排湿。
这将由185个产生气流的风扇和喷雾冷却系统支持，以使风扇吹出的风和运动员保持凉爽。
the facade consists of overlapping, multi-layered eaves made of wood gathered from japan’s 47 prefectures while more than 47,000 medium and small-sized trees have been planted around the stadium. according to the organizers, accessible seating has been distributed on all tiers and floors of the interior, which will ensure visibility and comfort for wheelchair users. meanwhile, natural air will circulate to help discharge heat and moisture. this will be supported by 185 airflow-creating fans and mist-cooling systems to keep both fans and athletes cool.
立面由重叠的多层屋檐组成。” 隈研吾办公事务所说道。‘每个屋檐的下方都覆盖着小直径的百叶窗，目的是以适当的现代方式表达日本建筑中美丽屋檐的传统。屋顶的桁架结构结合了钢梁和中等横截面的层压木材，利用木材的轴向刚度将屋顶桁架因风或地震而产生的变形降至最低。
the facade consists of overlapping, multi-layered eaves,’ explains kengo kuma’s office. ‘the underside of each eave is covered with small-diameter wood louvers in an effort to express the tradition of beautiful eaves in japanese architecture in an appropriate contemporary manner. the roof has a truss structure which combines steel beams and laminated lumber with a medium cross-section, utilizing the axial stiffness of wood to minimize deformation of the roof trusses due to wind or earthquakes.’ see designboom’s previous coverage of the project here.
