Interview about Hoshino Jinja Shrine, winner of the A' Cultural Heritage and Culture Industry Design Award 2024

About the Project

It is an innovative approach that combines old and new technologies, such as the traditional Japanese traditional construction method that does not use any metal fittings, Ishiba-building and limit strength calculation based on modern structural analysis. The design, composed of horizontal and vertical lines, is highly aesthetic and has been described as attractive structural beauty based on the unique Japanese sense of beauty.

Your innovative fusion of traditional Japanese construction methods with modern structural analysis in Hoshino Jinja Shrine has earned significant recognition, including the Silver A' Design Award - could you elaborate on how this harmonious blend of old and new technologies shapes the shrine's distinctive character?

The covered hall plays an important role in protecting the main shrine from the elements. The plan to rebuild the main shrine building began because it was difficult to maintain the main shrine building due to the close proximity of the old and new buildings. The shrine officials hoped that the new covered hall would be a structure that would continue to protect the main shrine for another 100 to 200 years, while being preserved in this location for generations to come. In addition, the main shrine, which is designated as a cultural asset by the city, will be investigated, renovated, and restored.The new covered hall will be an architecture in which traditional construction methods and technologies are not antiquated but state-of-the-art through a fusion of high-dimensional clarification of traditional construction methods and technologies using modern structural analysis technology and traditional construction methods and technologies that are the work of the modern age. We hope that the building will be a landmark in the community, and at the same time, it will be an architecture that preserves the strength and comfort of wood and its traditions for future generations.

The Hoshino Jinja Shrine's design emphasizes horizontal and vertical lines to create what has been described as an "attractive structural beauty" - what inspired your approach to interpreting traditional Japanese aesthetic principles in this contemporary context?

In addition to the structural beauty that is inevitably created by the axial structure of “pillars” and “penetrations” of the traditional construction method, which has been handed down for hundreds of years, the addition of “penetrations” calculated by modern structural calculations creates more horizontal and vertical continuity in the structure, resulting in a design that combines the traditional and modern scientific perspectives. The result is a design that fuses the traditional viewpoints of the past with the scientific viewpoints of the present.

In designing Hoshino Jinja Shrine without metal fittings, how did you leverage modern limit strength calculations to ensure the structure's durability while maintaining the authenticity of traditional Japanese building techniques?

The government-subsidized project, “Creation of Design Methods and Performance Verification Experiments for Traditional Construction Methods,” conducted from 2010 to 2014, makes it possible to incorporate safety and versatility into traditional buildings from a scientific perspective based on structural mechanics clarification.This will ensure the safety of traditional buildings through modern structural calculations.

The copper-sheet roof and gabled design of Hoshino Jinja Shrine create a striking visual presence - could you share the philosophical and practical considerations that influenced these architectural choices?

The design of the building has once again become a landmark in the community, as it has retained the design of the old covered hall that was built more than 100 years ago and was well known in the community.

How does Hoshino Jinja Shrine's role as a training site for students, engineers, and officials contribute to preserving traditional Japanese architectural techniques while fostering innovation in contemporary sacred architecture?

This architecture contributes to the succession of technology and the revitalization of local industry by evolving traditional techniques and designs, both old and new, and being publicly recognized both domestically and internationally with architectural and design awards.

The masonry structure of Hoshino Jinja Shrine was specifically designed to withstand earthquakes and typhoons - could you detail the innovative engineering solutions that make this possible without compromising the shrine's traditional aesthetic?

The government-subsidized “Design Method Development and Performance Verification Experiments of Traditional Construction Methods” conducted from 2010 to 2014 will make it possible to incorporate safety and versatility into traditional buildings from a scientific perspective by clarifying structural mechanics.The inheritance of traditional technology is not an old-fashioned business, but rather, by turning the scientific scalpel to the technology and construction methods in recent years, we believe that the buildings will be at the cutting edge of technology.

In creating Hoshino Jinja Shrine as a local landmark that contributes to tradition, culture, industry, and the environment, how did you balance these diverse objectives while maintaining the sacred character of the space?

The recent trend toward standardized, mass-produced construction and construction methods that rely on new construction materials and laminated wood has led to a steady decline in traditional techniques, which is difficult to maintain.This building will function as a place for universities, technical colleges, and other professional organizations in the prefecture to learn about traditional techniques, and to train future generations to carry on these techniques.

The Hoshino Jinja Shrine project spanned from August 2019 to December 2021 - what were the most challenging aspects of preserving traditional craftsmanship while implementing modern structural innovations during this period?

The two main goals were to nurture young craftsmen who would be the next generation to build and preserve traditional architecture for a long time, and to secure human resources for the severe conditions of the mountains in the exhausted region.

As Hoshino Jinja Shrine serves as both a sacred space and an educational venue, how did you design the space to accommodate these dual functions while maintaining its spiritual integrity?

Instead of designing, the shrine carpenter and designer himself was a craftsman who conveyed the importance of traditional techniques and wood as well as education and the sanctity of the shrine through on-site practical work.

Looking at the future impact of Hoshino Jinja Shrine's innovative design approach, how do you envision this project influencing the evolution of traditional Japanese architectural practices in contemporary sacred spaces?

The covered hall of the shrine has an important role in protecting the main shrine building from the elements. This reconstruction plan was based on the request of a sustainable structure for another 100~200 years to serve in a community so that traditional construction methods, *Ishibadate, and the calculation method of response and limit strength, are adopted. The main hall is designated as Cultural Asset by the city and will be renovated and restored. This main hall inherits ancient techniques, and the covered hall is new architecture that combines traditional and modern structural analysis techniques*Ishidatea setup where pillars stand on stones instead of being fixed deep into the ground
