Interview about Takanabe Ninomaru Historic Museum, winner of the A' Cultural Heritage and Culture Industry Design Award 2025

About the Project

Takanabe Historical Museum, established in 1986, was reimagined to address declining visitor engagement due to outdated exhibits. The redesign embraced JIN, the philosophy of benevolence, transforming it into a cultural and educational hub fostering civic pride. Through visual storytelling and spatial design, the renewal introduced thematic curation, immersive exhibitions, and layered acrylic panels symbolizing historical continuity. Renamed Ninomaru History Museum, it now serves as an interactive space where heritage, education, and community connect.

Your innovative transformation of Takanabe Ninomaru Historic Museum through visual storytelling and spatial design has garnered significant recognition, including the Gold A' Design Award - could you elaborate on how you developed the concept of JIN (benevolence) as the philosophical foundation for this cultural revival project?

Philosophical Foundation: JINThe project established JIN (benevolence), a Confucian virtue, as its central philosophical framework. Rooted in the ethical principles of the Akizuki clan that once governed Takanabe, this concept aimed not merely to restore the physical structure but to reconstruct the civic and moral values embedded within the region’s historical context. By integrating JIN into spatial composition and information design, the project re-contextualized historical ethics as a contemporary civic principle, transforming an abstract virtue into a tangible social form through design.

The acrylic panel installation at Takanabe Ninomaru Historic Museum, displaying successive lords and their policies with a red gradient symbolizing historical continuity, creates a striking visual narrative - what inspired this specific design choice and how does it enhance visitors' understanding of local heritage?

Acrylic Panels and the Red GradientThe acrylic panels depicting successive lords and their policies were designed to visualize the temporal continuity inherited across generations. Through the use of transparent acrylic with a red gradient, the design enables visitors to perceive the accumulation of time as overlapping layers of varying density. This visual system allows history to be understood not as a collection of discrete events but as an interconnected chain of succession and transformation. The gradation of color symbolizes the deepening of collective memory over time.

Given the challenge of limited historical materials and budget constraints at Takanabe Ninomaru Historic Museum, how did you leverage graphic and spatial design elements to create an immersive exhibition experience that effectively engages modern audiences?

Exhibition Design under ConstraintsFaced with limited archival materials and a restricted budget, the project emphasized narrative construction through graphic and spatial design. Controlled use of light, texture, and typographic hierarchy allowed for an immersive experience without dependence on artifact volume. Minimal visual language and rhythmic sequencing compensated for material scarcity, promoting intellectual focus and emotional engagement. This approach demonstrates how spatial semiotics can serve as an effective interpretive strategy in heritage presentation.

The rebranding of Takanabe Ninomaru Historic Museum appears to have successfully balanced historical authenticity with contemporary design elements - could you share your approach to maintaining this delicate equilibrium while fostering civic pride?

Balancing Historical Authenticity and Contemporary InterpretationThe design sought to preserve historical authenticity while ensuring accessibility for contemporary audiences. Rather than reproducing traditional motifs or materials, the design extracted and restructured their underlying geometries and compositional rhythms. The combination of wood and acrylic materials symbolizes permanence and transparency—representing a dialogue between the past and the present. This dual structure allows the museum to function both as a site of preservation and as a civic platform for reconstructing local identity.

In reimagining Takanabe Ninomaru Historic Museum's exhibition spaces, how did your previous experience as a creative director influence your strategy for integrating educational content with engaging visual presentations?

Influence of Creative Direction ExperiencePrior experience in brand and communication design informed the exhibition framework. Methods such as structural hierarchy, editorial rhythm, and narrative sequencing were applied to ensure coherence across graphic, spatial, and textual layers. The exhibition was organized as a narrative structure—introduction, development, and reflection—allowing educational content to be received as both intellectual and affective experience.

The zoning design and sequential flow of Takanabe Ninomaru Historic Museum creates an intuitive learning journey - could you explain the thought process behind this spatial arrangement and how it enhances the visitor experience?

Zoning and Spatial Sequence (Revised)The spatial composition was designed as a two-level structure: the first floor dedicated to historical archives and the second to narrative exhibition. The first level introduces factual materials and chronological data, while the second transitions visitors into a more immersive, story-driven experience through graphics, video, and installations. The zoning of themes—policy, education, and community—was based on a psychological progression from observation to emotional immersion and comprehension. Subtle thresholds were introduced along the circulation path, enabling understanding through spatial rhythm rather than textual explanation.

Your integration of the 7th lord Akizuki Taneshige's policies with modern SDGs concepts at Takanabe Ninomaru Historic Museum is particularly intriguing - how did you conceptualize this connection between historical governance and contemporary sustainability goals?

Akizuki Taneshige’s Governance and the SDGsResearch on the seventh lord, Akizuki Taneshige, revealed governance principles consistent with contemporary sustainability values, such as forest management, public education, and equitable water distribution. These policies were compared with the United Nations’ Sustainable Development Goals (SDGs), highlighting structural parallels between early modern administration and present sustainability frameworks. Infographics were employed to visualize these correspondences, presenting historical governance as a prototype for sustainable regional management.

The transformation of Takanabe Ninomaru Historic Museum from a declining institution to a vibrant cultural hub represents a significant achievement in cultural preservation - what key insights from this project could benefit other historical institutions facing similar challenges?

Implications for Other Cultural InstitutionsThe project demonstrates that regional museums can achieve revitalization through clear narrative frameworks and participatory processes, even under economic constraints. Collaboration among historians, designers, and municipal officials redefined the museum from a static preservation site to a communicative cultural infrastructure. This case provides a model for integrating heritage conservation with community engagement, positioning design as a medium for cultural regeneration.

Looking at the future of Takanabe Ninomaru Historic Museum, how do you envision the space evolving to maintain its relevance while continuing to honor and preserve local heritage?

Future DevelopmentFuture plans envision the museum as an interdisciplinary platform connecting education, regional culture, and industry. The focus will shift from quantitative expansion of exhibits to qualitative deepening through participatory programs. Collaborations with local producers and educational institutions will link the exhibition to regional economies and cultural practices, ensuring its sustainability as a dynamic public resource that continues to generate relevance over time.

The extensive research and expert consultations that informed Takanabe Ninomaru Historic Museum's narrative development must have revealed fascinating historical insights - could you share some unexpected discoveries that significantly influenced your final design decisions?

Archival Discoveries and Their ImpactArchival research uncovered letters from local farmers expressing gratitude for Akizuki’s administrative reforms. These documents provide primary evidence of the reciprocal relationship between governance and community. Incorporating these materials reoriented the exhibition from a ruler-centered narrative to one that includes the perspective of ordinary citizens. This reframing introduced the concept of mutual recognition as a foundation for social cohesion, offering a new interpretive model for historical exhibitions.
