该幼儿园位于东京市中心町屋的高架铁路下。该项目是一项倡议，通过利用高架铁路下的空间来解决幼儿园的短缺问题。这是因为日本的城市地区缺少幼儿园，但却没有可以建造幼儿园的场地。
The nursery school is located under the elevated railway in Machiya, downtown Tokyo. The project is an initiative to solve the shortage of nursery schools by using spaces under elevated railways. This is because there is a shortage of nursery schools in urban areas in Japan, but there are no sites on which to build them.
高架铁路建于1931年。高架铁路下建有商店和房屋，形成了市中心的景观，生活气息溢于言表，但为了给高架结构的抗震加固让路，他们被驱逐了。抗震加固后，该地块空置了很长时间，但已开始重新利用，首先是幼儿园的计划。
The elevated railway was built in 1931. Shops and houses were built under the elevated railway, forming a downtown landscape where life overflowed into the streets, but they were evicted to make way for seismic reinforcement of the elevated structure. After seismic reinforcement, the site remained vacant for a long time but has begun to be re-used, starting with plans for the nursery school.
近年来，幼儿园已经被关闭，孩子们和镇上的人们变得疏远了。我们想创造一个对镇上开放的幼儿园建筑，这样镇上的人就可以期待着看孩子们的成长。横跨小镇的老式高架结构，梁下高度约为3.9米，很低。跨度也很短，约6米，给人一种沉重的感觉。我们创造了一个67米长的大屋顶，以协调高架结构的规模和建筑的规模之间的关系。水平延伸的屋顶创造了关于街道的幼儿园的外墙。在内部，屋顶叠加在高架结构上，形成了一个柔和的、避开车站区喧嚣的幼儿园空间。
In recent years, nursery schools have been closed to the town, and the children and the people of the town have become estranged. We wanted to create a nursery school architecture that is open to the town so that the people of the town can look forward to watching the children's growth. The old, elevated structure crossing the town is low at a height of about 3.9 m under the girders. The span is also short at about 6 m, giving it a heavy impression. We created a large 67 m long roof to harmonize between the scale of the elevated structure and the scale of the architecture. The horizontally extending roof creates the facade of the nursery school about the street. On the inside, the roof is superimposed on the elevated structure to form a soft and sheltered nursery school space from the station area's hustle and bustle.
幼儿园的房间分布在大屋顶下的三个群组中，横跨一个操场，和一个沙坑。每个房间都由沿街屋檐下的半户外空间连接。幼儿园的活动出现在街道上，在这个39米长的屋檐空间的轴线上，每个高架结构之间有一个清洗区、游乐设备、自行车停放区和一个入口门廊。
The nursery rooms are distributed in three clusters under the large roof, across a playground, and a sandpit. Each room was connected by a semi-outdoor space under the eaves along the street. The activities of the nursery school appear in the street, with a washing area, play equipment, a bicycle parking area, and an entrance porch between each elevated structure on the axis of this 39 m long eaves space.
操场是一个独特的半户外空间，由高架结构和建筑的叠加而形成。由于热岛效应，夏季的城市气候正变得越来越严重。作为主要的屋顶，高架结构保护操场免受强烈阳光的照射。建筑的屋顶保护人们的活动不受雨水影响，并作为一个光架，用反射光照亮操场。高架结构下固有的黑暗被颠覆了，使操场在夏季更容易接近，高架天花板被明亮地照亮。
The playground is a unique semi-outdoor space created by the superimposition of the elevated structure and architecture. The urban climate in summer is becoming increasingly severe due to the heat island effect. As the primary roof, the elevated structure protects the playground from strong sunlight. The roof of the architecture protects the movement of people from rain and acts as a light shelf to illuminate the playground with reflected light. The darkness inherent under the elevated structure is overturned, making the playground more accessible in the summer months, with the elevated ceiling brightly illuminated.
幼儿园通过深深的屋檐与城镇相连。屋檐所产生的安全感使这个地方大胆地向城镇开放，但又受到保护。镇上许多人喜欢沿着幼儿园种植的季节性花卉和植物。幼儿园被创建在一个类似于市中心的距离，沿着街道行走可以瞥见幼儿园的日常生活，就像一幅画卷，交流自然而然地发生了。
The nursery school was connected to the town through deep eaves. The sense of security created by the eaves made the place boldly open to the town yet protected. Many people in the town enjoy the seasonal flowers and plants planted along the nursery school. The nursery school was created at a downtown-like distance, where walking along the street gives a glimpse of the nursery's daily life like a picture scroll, and communication naturally takes place.
