PlanetDAO: A Groundbreaking Initiative to Preserve Japan's Historic Properties

In an impressive display of global collaboration, the innovative initiative known as PlanetDAO has just won the Grand Prize at the Japan Tourism NFT Awards 2025. This recognition comes as a result of their significant contributions to the preservation of Japan's historical buildings, supported by 289 contributors from 23 countries who collectively donated over 100 million yen. The initiative, spearheaded by Planet Labs, a company focused on the restoration and management of historic properties, has employed a groundbreaking approach that merges local community interests with international backing to ensure the future of these cultural treasures.

The Concept of PlanetDAO

PlanetDAO operates on a model of ‘shared ownership’ utilizing decentralized autonomous organization (DAO) principles. The project allows community members who wish to preserve their local historical structures to bond with international supporters. Importantly, it offers community stakeholders voting rights regardless of their financial contributions, fostering an environment of co-creative governance. The unique approach was notably praised for enabling local residents to engage actively in management, a stark contrast to traditional models of historical site preservation.

Spotlight on Two Key Projects

As part of the award ceremony, PlanetDAO showcased ongoing initiatives in Wakayama Prefecture and Niigata Prefecture, exemplifying their commitment to integrating community voices into the preservation process. Here’s a closer look at these projects:

1. Revitalization Project in Nachi Katsuura, Wakayama

The project in Nachi Katsuura entails the revival of a historic temple, registered as a tangible cultural property, which was facing deterioration due to both depopulation and a lack of resident priests. This 170-year-old temple is being converted into accommodations, breathing new life into a once neglected space. Approximately 80% of the project’s stakeholders hail from overseas, showcasing the scope of global support pouring in for Japan's cultural heritage.

Voices from International Contributors:

- Julie (Philippines): “I spent six months in Wakayama in 2023. My desire to preserve the beauty and culture of this area is profound.”
- Julio (UK): “If local tourist spots continue to cater solely to low-wage labor, they lose their unique essence. I want to support collecting funds while preserving the region's identity.”
- Mark (Bangkok): “Having lived in Japan for seven years, I adore Wakayama. I resonate with PlanetDAO’s ambitious approach and wanted to contribute.”
- Amelia (Singapore): “After walking the Kumano Kodo last year and discovering PlanetDAO, I felt compelled to get involved.”

Comments from the Temple Priest, Tōmi Nishiyama:
“In the past, our temple was supported by just a limited number of parishioners. Now, we are entering an era where ‘global fans’ become owners and support us. I want to pass on this legacy in an even brighter form to future generations.”

2. Restoration Project at Hojo Family Residence in Sado, Niigata

The Hojo family residence, recognized for over 350 years of providing medical assistance using traditional Chinese medicine, has also faced maintenance challenges. With financial and physical constraints, the future of this residence is at stake. The PlanetDAO project will transform structures like rice stores into lodges and experiential sites, utilizing the framework of shared ownership to ensure sustainable management.

Voice from Tada Hojo, a Descendant of the Family:
“Maintaining a cultural property without governmental aid is a burden solely on the owner; we’ve personally spent millions to restore it. The potential that PlanetDAO gives us to include stakeholders and the community in decision-making was the strongest motivator for our participation.”

Judges’ Remarks

Judge Koichi Ishii praised the versatility of the PlanetDAO initiative, emphasizing its applicability to various tourism and heritage contexts. “The project could support local tourism assets like hot springs and inns, offering hope for revitalization in areas struggling to attract visitors.”

Reflection from Planet Labs President, Takaki Nishimura

Nishimura reflected on the award by stating that historical buildings hold intangible value that economic metrics cannot capture. The recognition illustrates that the collaborative efforts of locals and global supporters can reshape the narrative of cultural heritage from merely a tourism resource to a shared future. Looking forward, PlanetDAO aims to continue this mission of preserving and transmitting Japan’s rich heritage to future generations.

Concluding Thoughts and Future Engagement

The remarkable achievements of PlanetDAO show how global collaboration can breathe new life into historical sites while honoring local traditions. As interest in these programs grows, there will be opportunities for further engagement. Upcoming events include “Co-Owner Stayovers” where participants can witness first-hand the transformations occurring at the Hojo family residence in Sado.
