3D Digital Archive of Eirakukan Theater

In a groundbreaking initiative, HoloLab has successfully created a 3D digital archive of the Eirakukan Theater, located in Toyooka City, Hyogo Prefecture. This project not only aims to preserve the rich cultural heritage of this historic venue but also leverages modern technology to promote local tourism and community development.

Founded in 1901 by Kiichiro Obata, the Eirakukan Theater is renowned as the oldest playhouse in the Kinki region. It served as a cultural hub in the Tajima area, showcasing various performance arts such as Kabuki, traditional theater, and silent films from the Meiji Era to Showa. However, the theater faced closure in 1964 due to changing entertainment trends and the rise of television, leading to a decline in live performances. After a robust preservation movement by local residents and significant restoration efforts from 2006 to 2008, the theater reopened, fully restoring its historical architecture and stage mechanisms.

Innovative Technology in Action

HoloLab utilized a combination of advanced 3D scanning techniques to capture the theater's intricate details. The project employed the RTC360 terrestrial laser scanner for high-precision point cloud data, the α7RV mirrorless camera for detailed photography, and the XGRIDS Lixel K1 handheld laser scanner for flexible scanning in tight spaces.

With over 6,000 photographs taken, the project relied on both photogrammetry and 3D Gaussian Splatting techniques, allowing for a highly realistic virtual representation of the theater. Users will soon be able to explore the newly created virtual space, named ‘Eirakukan VR’, which is set to go live on August 28, 2026. Accessible through web browsers on computers and mobile devices, this platform eliminates the need for special applications, providing a seamless visitor experience.

The Significance of Digital Preservation

The digital archive of the Eirakukan Theater is not solely focused on preserving its history. HoloLab views this initiative as a valuable example of ‘Regional Digital Transformation’ (DX), promoting local assets to attract tourism and enrich educational resources. The 3D digital archive not only preserves the past; it connects communities with their history and encourages future generations to embrace their cultural heritage.

The collaboration with various stakeholders, including the Eirakukan Theater, Toyooka City, and the Hyogo Prefectural Government, establishes a strong foundation for future projects aimed at cultural education and tourism.
