校园与社区的桥梁：该项目的核心亮点在于其对社区开放性的强调。设计师巧妙地将出售土地可能导致的活动空间压缩问题转化为机遇，通过设计一个与校园相连的三层阶梯式露台，创造了孩子们嬉戏玩耍的公共空间。这种设计不仅弥补了活动空间的损失，更重要的是，它将学校与社区紧密联系起来。阶梯露台成为连接校园与街道的桥梁，让学校的日常活动融入当地社区的日常生活，从而消除了潜在的隔阂，实现了建筑与环境的和谐共生，这是该项目在社会层面上的重要贡献。

空间与功能的灵活应对：项目的精髓体现在对空间灵活性的极致追求。考虑到地基条件和未来使用的多样性，设计师采用了创新的地基置换法，降低了施工成本，同时也为建筑的轻盈感奠定了基础。轻型钢框架结构的使用，搭配开放式刚架结构体系，赋予了建筑内部空间极高的灵活性。通过可完全打开的隔断，教室可以灵活地与公共区域连接，满足不同教学需求。这种设计理念不仅提升了空间利用率，也为未来的功能调整提供了极大的便利，体现了建筑师对可持续性和未来性的深刻思考。

技术创新与材料的巧妙运用：该项目在技术层面展现了极高的专业水准。在地基处理上，设计师没有采用传统的长桩施工法，而是大胆尝试了地基置换法，这种方法在保证建筑安全的同时，也节约了成本。此外，轻型钢框架结构和灵活的开放式刚架结构的运用，不仅减轻了建筑的自重，也为空间的自由组合提供了可能。在材料的选择上，设计师注重结构的简洁性，减少构件数量，从而进一步降低了建筑的重量。这些技术创新和材料的巧妙运用，使得该项目在有限的条件下实现了功能和美学的完美结合，展现了建筑师对技术和材料的深刻理解。

Koreans in Japan and Korean Schools

The term "Koreans in Japan" refers to people who immigrated to Japan from the Korean Peninsula after the merger of Japan and South Korea in 1910, or their descendants.. North Korean schools are places where Japanese and Korean children learn about their roots and mother tongue. Currently, there are 51 North Korean schools scattered throughout Japan. Among them, Kawasaki Korean School was founded in 1946 and is a relatively small school with a total of about 40 students, as well as primary and preschool classes.
在日朝鲜人及朝鲜学校

“在日朝鲜人”一词指的是 1910 年日韩合并后从朝鲜半岛移民至日本的人，或他们的后代。朝鲜学校是在日朝鲜儿童了解自身根源与母语的地方。目前，日本全国散布着 51 所朝鲜学校。其中，川崎韩国学校于 1946 年创办，是一所规模较小的学校，总共有约 40 名学生，并附设小学和学前班。

Ladder style terrace as campus expansion space

The school will sell some land to raise funds for the construction of new school buildings.. Therefore, initially people were very concerned that selling some land would compress children's activity space. In response to this issue, the design team adjusted the volume of the two-story building and proposed to create an open three-level terrace connected to the campus for children to play on.
阶梯式露台作为校园拓展空间

学校将部分土地出售，以筹集新建校舍的资金。因此，起初人们非常担忧出售部分土地会压缩孩子们的活动空间。针对这一问题，设计团队调整了两层建筑的体量，并提议打造一个与校园相连的开放式三层阶梯露台，供孩子们玩耍。

Stage turned into local scenery

For this new North Korean school, opening up to the surrounding environment is a core theme that goes beyond its history of discrimination in Japan.. As the activities on the terrace can be seen from the street, this three tiered terrace has become a stage for the town. The scene of children running and playing on the terrace has become a daily sight in the local community. The activities on the terrace blend seamlessly with the surrounding environment, and the design team also intends to make this North Korean school a part of the local scenery.
舞台化作当地风景

对于这所新朝鲜学校而言，向周边环境敞开怀抱是超越其在日本遭受歧视历史的核心主题。由于从街道上就能看到露台上的活动，这个三层阶梯露台便成了小镇的一个舞台。孩子们在露台上奔跑玩耍的景象，成了当地社区的日常一景。露台上的活动与周边环境相互交融，设计团队也有意让这所朝鲜学校成为当地风景的一部分。

Foundation replacement method and construction of lightweight steel frame structure

The site is adjacent to the reclamation area along the coast of Kawasaki Port, and the foundation is extremely soft.. We did not use the long pile construction method, but instead adopted the foundation replacement method, which prevents uneven settlement by making the weight of excavated soil equal to the weight of the building, thereby reducing construction costs. The balance weight is adjusted by embedding polystyrene foam under the underground concrete slab. To implement this method, the design team minimized the number of components as much as possible to reduce the weight of the steel structure.
地基置换法与轻型钢框架结构施工

该场地毗邻川崎港沿岸的填海造地区，地基极为松软。我们未采用长桩施工法，而是采用了地基置换法，通过使挖出土方的重量与建筑物重量相等来防止不均匀沉降，从而降低了施工成本。平衡重量通过在地下混凝土板下方埋设聚苯乙烯泡沫来进行调节。为实现这一方法，设计团队尽可能减少构件数量，以减轻钢结构重量。

Open frame structure

This steel structure adopts a frame structure system and is equipped with partially centrally arranged support components to enhance overall stiffness.. When adjusting the dimensions of structural components, the design team prioritizes obtaining flexibility by constructing a clear and defined rigid frame spatial layout. The design team fully considered the flexibility required to cope with various future uses and changes in usage. The doors that separate each room can be fully opened, allowing the classroom to be connected to public areas or used as a whole, thus effectively utilizing limited space.
开放式刚架结构

该钢结构采用刚架结构体系，并配有部分集中布置的支撑构件以增强整体刚度。在调整结构构件尺寸时，设计团队优先考虑通过构建清晰明确的刚架空间布局来获取灵活性。设计团队充分考虑到了应对未来各种用途及使用变化所需的灵活性。分隔各房间的门均可完全打开，使得教室能够与公共区域相连通或作为一个整体使用，从而有效利用有限的空间。

Symbol of Openness

The design team hopes that this stepped terrace extending from the campus to the classrooms can become a bridge between Japanese Koreans and the local community, and become a new symbol of openness for Japanese Korean schools..
开放的象征

设计团队希望，这个从校园延伸至教室的阶梯式露台，能够成为在日朝鲜人与当地社区之间的桥梁，成为日本朝鲜学校崭新的开放象征。
