项目 - 在日本关东平原的中心地带，第二抚子幼儿园以其创新设计矗立于此，这座精心设计的教育设施巧妙地将建筑创新与环境意识融为一体。这个新落成的项目可容纳200多名儿童，在日本最炎热的城市熊谷，它完美地回应了教育需求与气候挑战。

建筑最引人注目的特征是其独特的屋顶线条，它诗意地映射了周围的山脉轮廓。从富士山到筑波山，建筑形态与这些标志性山峰展开视觉对话，将当地景观融入儿童的日常体验中。这一设计选择将建筑转化为记忆制造装置，让幼年经历与地域地理产生内在联系。

这座两层建筑采用钢筋混凝土与木材相结合的混合结构系统。底层容纳0-2岁儿童的设施，采用坚固的混凝土结构以承受活跃的游戏活动，而容纳3-5岁儿童的上层则采用更为轻盈的木质结构。尽管防火规范要求用耐火石膏板覆盖复杂的木框架，但这种结构组合使建筑标志性的自由形态屋顶得以实现。

为应对熊谷极端的炎热天气，建筑师实施了多重降温策略。建筑达到最高隔热等级（4级），二层的外部百叶窗提供必要的遮阳控制。设计包含有遮阳走廊、骑楼和檐廊，创造重要的阴凉区域，并配备创新的喷雾系统，利用蒸发制冷原理。

该设施与室外空间的关系特别值得关注。每间教室都与室外保持紧密联系，连接着精心设计的空间，包括安全的庭院、有顶广场和与周围乡村景观融为一体的开放式平台。这种布局让孩子们可以自由选择他们喜欢的环境，同时通过细心的监护确保他们的安全。

团队 – 川久保智康建筑设计事务所成立于2005年，是一家位于东京的建筑事务所，凭借其创新的住宅和商业项目在建筑界掀起波澜。在建筑师川久保智康的带领下，这个紧密团结的团队以全新的创造力面对每一个委托项目。

川久保智康最初在著名的矶崎新建筑事务所工作，随后于2002年开始独立执业。他对空间规划的精通和对细节的敏锐洞察力，在其设计中得到充分体现，既确保功能最大化，又表达出独特的美学视野。事务所的住宅作品，如获奖的藏前小住宅（Kuramae Small House）和西原联排住宅（Nishihara Row Houses），展现了他们在受限的城市场地中打造高度宜居空间的能力。

在川久保的领导下，事务所采用跨学科的方法，经常模糊建筑与产品设计之间的界限。这种交叉融合创造出引人入胜的环境，定制家具和装置与建筑理念完美融为一体。

除了设计创新建筑，事务所还深度参与建筑教育。川久保自2014年起在日本大学工学院任教，并担任客座研究员，致力于培养新一代人才。

通过获得国际赞誉的建成作品和对推进建筑行业的承诺，川久保智康建筑设计事务所已确立其作为日本最令人兴奋的新兴建筑事务所之一的地位。

Feature：

Project - In the heart of Japan's Kanto Plain, Dai 2 Nadeshiko Nursery School emerges as a thoughtfully designed educational facility that harmoniously blends architectural innovation with environmental consciousness. This newly completed project, accommodating over 200 children, represents a sophisticated response to both pedagogical needs and climatic challenges in Kumagaya, famously known as Japan's hottest city.

The building's most striking feature is its distinctive roofline, which poetically mirrors the surrounding mountain ranges visible from the site. From Mount Fuji to Mount Tsukuba, the architectural form creates a visual dialogue with these iconic peaks, embedding the local landscape into the children's daily experience. This design choice transforms the building into a memory-making device, where early childhood experiences are intrinsically linked to the regional geography.

The two-story structure employs a hybrid construction system that combines reinforced concrete and timber. The ground floor, housing facilities for children aged 0-2, utilizes robust concrete construction to withstand active play, while the upper level, dedicated to 3-5 year olds, features a more delicate wooden structure. Although fire regulations necessitate covering the complex wooden framework with fire-resistant plasterboard, this combination enables the creation of the building's signature free-form roof.

In response to Kumagaya's extreme heat, the architects implemented multiple cooling strategies. The building achieves the highest insulation rating (Grade 4), while external blinds on the second floor provide essential solar control. The design incorporates covered walkways, pilotis, and eaves that create vital shade, complemented by an innovative mist system that leverages evaporative cooling.

The facility's relationship with its outdoor spaces is particularly noteworthy. Each classroom maintains a strong connection to the exterior, opening onto a series of thoughtfully designed spaces including a secure courtyard, covered plaza, and open decks that merge with the surrounding rural landscape. This arrangement gives children the freedom to choose their preferred environment while ensuring their safety through careful oversight.

Design Team - Founded in 2005, Kawakubo Tomoyasu Architects is a Tokyo-based architectural firm making waves with their innovative residential and commercial projects. Led by principal architect Tomoyasu Kawakubo, a first-class certified architect, the firm's tight-knit team approaches each commission with fresh creative energy.

Kawakubo cut his teeth at the renowned Isozaki Arata & Associates before branching out on his own in 2002. His mastery of spatial planning and keen eye for detail shine through in designs that maximize functionality while expressing a distinct aesthetic vision. The firm's residential work, such as the award-winning Kuramae Small House and Nishihara Row Houses, demonstrates an ability to craft highly livable spaces on constrained urban sites.

With Kawakubo at the helm, the practice embraces an interdisciplinary approach, often blurring the lines between architecture and product design. This cross-pollination results in compelling environments where customized furniture and fixtures seamlessly integrate with the architectural concepts.

Beyond designing innovative buildings, the firm is deeply engaged in architectural education. Kawakubo has taught at Nihon University's College of Engineering since 2014 and serves as a visiting researcher, nurturing the next generation of talent.

Through built works earning international acclaim and a commitment to advancing the profession, Kawakubo Tomoyasu Architecture & Associates has cemented its position as one of Japan's most exciting emerging practices.
