(奄美イノベーション株式会社_{Amami Inobēshon Kabushiki Gaisha}^Japanese) in 2016, and Denpaku+Kogei Inc. (株式会社伝泊＋工芸_{Kabushiki Gaisha Denpaku+Kōgei}^Japanese) in 2019, which focuses on expanding the Denpaku concept nationwide. He also established the General Incorporated Association Shima Hito Takara (一般社団法人しま・ひと・たから_{Ippan Shadan Hōjin Shima Hito Takara}^Japanese) in 2019 to promote community development with local individuals and businesses, and the General Incorporated Association Wellness.M (一般社団法人ウェルネス.M_{Ippan Shadan Hōjin Werunesu.M}^Japanese) in 2021 to support medical professionals and individuals in workation programs.

3.2. Urban Micro-Architecture and Notable Designs

Yamashita gained significant international recognition for his innovative approach to urban micro-architecture, particularly through his designs for compact houses in dense urban environments. In 2004, his project 'Cell Bricks', an urban micro-house located in Tokyo, earned him the AR Emerging Architecture Award. That same year, he won an international design competition for the Busan Eco-Center (Nakdong Estuary Eco-Center) in Busan, South Korea. This museum is dedicated to the conservation of local waterbirds and the surrounding environment, showcasing his ability to blend architectural design with ecological awareness. Another notable early work was 'Crystal Bricks', which received the Gold Prize at the 11th Space Design Competition in 2004.

3.3. Disaster Relief and Reconstruction

Yamashita has been deeply committed to disaster relief and reconstruction efforts since the Great Hanshin earthquake in 1995. Following the devastating 2011 Tōhoku earthquake and tsunami, he actively participated in recovery initiatives. A significant project was the community home named "Home-for-All for Fishermen in Kamaishi," designed in collaboration with Toyo Ito & Associates. This project provided a crucial communal space for those affected by the disaster.

In 2013, a collective of architects known as TeMaLi Architects, including Yamashita, won the design competition for a post-disaster public housing project in Kamaishi, Iwate. This housing project was highly acclaimed, receiving the LEAF Awards 2013, an international architectural award. Two other projects by Yamashita, 'Boundary House' and 'Emergency Supply Warehouse', also received LEAF Awards in the same year, demonstrating his comprehensive involvement in disaster-resilient and sustainable architectural solutions.

3.4. Regional Material Utilization and Innovative Construction

In 2013, Yamashita founded the Regional Material Utilization Network (General Incorporated Association for Regional Material Utilization, 一般社団法人地域素材利活用協会_{Ippan Shadan Hōjin Chiiki Sozai Rikatsuyō Kyōkai}^Japanese). This institute serves as a vital platform for identifying and re-editing local materials and construction methods from various regions. The goal is to generate new economic opportunities and foster community revitalization through architectural endeavors.

One prominent example of his innovative use of regional materials is the 'R-torso-C' project. This private residence was constructed using SHIRASU concrete, a specialized concrete that incorporates シラス_SHIRASU^Japanese, a deposit of pyroclastic flow (volcanic ash) found in Kagoshima Prefecture, Japan, as a fine aggregate. The 'R-torso-C' project garnered significant domestic and international acclaim, receiving the Japan Concrete Institute Awards in 2016, the American Concrete Institute (ACI) Excellence in Concrete Construction Awards in 2017 (winning the Overall Excellence Award and first place in the Low Rise Category), and the fib (Fédération internationale du béton) Awards for Outstanding Concrete Structures in 2018 (winner in the Buildings Category). These awards underscore Yamashita's success in elevating regional materials into globally recognized architectural innovations.

3.5. Amami-centered Regional and Cultural Revitalization (Denpaku)

Yamashita has spearheaded a comprehensive regional revitalization project centered in his hometown, Amami Oshima. In 2016, he initiated the 'Denpaku' (伝泊_Denpaku^Japanese) project, which involves renovating vacant houses across Amami to convert them into unique lodging facilities. The primary aim of Denpaku is to preserve and transmit the "traditional and legendary architecture, community, and culture" of Amami to future generations, fostering a deeper connection between visitors and the local heritage. Amami Innovation Inc. was established to operate these Denpaku facilities.

In July 2018, Yamashita further expanded his efforts by renovating a former supermarket in Kasari-cho, Amami City, and opening a community center called "Denpaku + Magun" (伝泊ホテル+まーぐん広場・赤木名_{Denpaku Hoteru + Magun Hiroba Akakina}^Japanese). This innovative complex functions as a multi-purpose hub, encompassing tourist accommodations, facilities for the elderly, an eatery, and a food mart. In this particular project, Yamashita assumed the dual role of both architect and head of facility management, demonstrating his hands-on commitment to community building. The integrated approach of Denpaku and Magun Hiroba received the prestigious Minister of Land, Infrastructure, Transport and Tourism Award (the highest honor) and the Ethics Award at the 6th Japan Tourism Awards in September 2020, recognized by the United Nations World Tourism Organization (UNWTO) for its concept of "Tourism as a daily life" that connects visitors with local culture.

Following the success of Denpaku in Amami, Yamashita established Denpaku+Kogei Inc. in May 2019, with the goal of expanding the Denpaku concept nationwide. The first such expansion, "Denpaku Komatsu," opened in April 2021. Additionally, to further promote community and wellness, he established the General Incorporated Association Shima Hito Takara in November 2019, collaborating with local individuals, businesses, Japan Airlines, and IT companies to advance urban development. In April 2021, he also founded the General Incorporated Association Wellness.M to support workation programs for medical professionals, individuals, and corporations. Further enhancing the luxury tourism aspect of Amami, the "2 waters" facility, featuring a reception, restaurant & bar, and an outdoor infinity pool, opened in April 2021, completing the high-end resort adjacent to "Denpaku The Beachfront MIJORA".

3.6. Academic Activities

He also held part-time lecturer positions at Tokyo University of Science from 2008 to 2010 and Keio University's Graduate School from 2010 to 2012. From April 2011 to March 2013, he was a part-time lecturer at Kyushu University, where he subsequently became a visiting professor from July 2013 to March 2019, conducting significant research on elderly facilities. In 2014, his firm integrated with Ma Design Office and LIFE+shelter associates, broadening his collaborative research and practical scope.
