Innovative solution to Japan's vacant property problem: building a community-driven property revitalisation platform using the Cardano blockchain.

> Problem

Japan has a growing problem of vacant houses in rural areas, which is hindering the revitalisation of local communities and the health of the property market. Conventional financial instruments have limitations in terms of financing and management, and a new approach is needed to utilize vacant houses effectively. This issue is not just for vacant but also true for overlooked resources and assets in local communities. We hope to provide a common solution for the problem.

In addition, while we have implemented a prototype on Ethereum and appealed to domestic web2.0 users for ease of use, there are currently few connections with overseas real web3.0 ecosystems. In aiming to become a fundraising platform using RWAs and DAOs in web 3.0 not just in Japan but globally, we believe it is necessary to work with Cardano to create connections with the web 3.0 ecosystem at home and abroad, while attracting international web 3.0 users.

> Prototype

The current prototype can be fully viewed here (schematic diagram of how it works):

Here is an overview of the current prototype.

ANGO-owned properties attract customers through various OTA sites (e.g. Airbnb) to generate main sales.The ANGO's properties are being developed and managed by DAOs for the properties.

DAO members contribute to the properties using their own expertise and receive reward tokens in return.Reward tokens can be redeemed for free nights in ANGO properties.

Currently ANGO is, A booking website for the general public, DAO members with their own token management screen.

> Value of prototypes

ANGO brings three values to solve local problems.

First, it improves property utilization.

Realistically, by industry standards, it is very difficult to achieve an annual property utilization rate of more than 50% by attracting guests through overnight stays alone. Therefore, by opening up available dates to DAO members, the property utilization rate can be increased greatly.

Second, it lowers operating costs.

By enlisting the help of DAO members, the development and operation of properties can proceed without inflating resources within the ANGO. Not only that, but because ANGO DAO members are located throughout the country, property development can proceed quickly and on a large scale.

Third, new jobs are created.

In the future, ANGO reward tokens will be redeemable for access to all RWAs. The more diverse the redemption opportunities, the more DAO members will be able to contribute their talents to the ANGO. New employment opportunities will be created here.

> Our approach

The ANGO project uses DAO and RWA NFT to transform vacant houses into attractive holiday homes run by the community. This will let people rediscover the attractiveness of the area and generate new economic activity, using the Cardano blockchain as a foundation, which will ensure transparency and attract investment from all over the world. we also hope to offer this platform to third party projects that share a similar vision.

In addition to our current prototype, we plan to Issue akiya property RWA NFTs to raise money from users. So users can own the RWA properties through DAO.

> Engagement

Local community members can be involved in the design and management of the project, thus creating a direct connection with the users. This builds trust and interest in the project and enables it to operate sustainably.

> Specificity

This project is the first attempt to utilize real-world assets (RWAs) together with DAOs on the Cardano blockchain and proposes a new model for local development using decentralized technology and organization model.

> Importance to Cardano

If the project is successful, it will provide an opportunity for Cardano technology to be accepted by more companies and regions. It will also increase its credibility with other developers and investors as an example of the practicality and scalability of the Cardano blockchain. We can potentially bring in more than 34 million users to the Cardano ecosystem in the long run.

> Setting KPIs (Key Performance Indicators)

To assess progress and achievements as an MVP, three KPIs are set as short-term targets.

1. Number of vacant house renovation projects: the number of vacant houses renovated within the timeframe from the start of the project is regularly measured. The target is to achieve 10 successful rehabilitations in the first year.
2. Users: number of people staying at the properties, local residents and members registered and actively involved in the platform. The target is to have 8000 users in the first year.
3. Annual occupancy rate: 36% (from past results)
4. Average number of guests: 6 (from past results)
5. Number of properties: 10 (from KPI 1 )
6. *Slightly discounted figure set as target to take account of duplication of guests.
7. Economic impact: the impact on the local economy is assessed in monetary terms, with indicators such as return on investment (ROI) and number of jobs created. The target is to generate a direct economic impact of at least 7.8 million dollar from the project in the first phase.
8. Number of users: 8,000 (from KPI 2)
9. Average tourism budget: 10,000 yen/stay (from ANGO)
10. Percentage allocated to employment: half of accommodation costs (hypothetical)

These KPIs are key indicators for measuring the specific impact of the project and are adjusted and optimized through regular reviews.

> Expected Impacts

We estimate that the benefits that ANGO can provide in the Long-Term in collaboration with Cardano are as follows

1. Number of vacant house renovation projects: 424,000 units.
2. Number of vacant houses in Japan: 8.48 million.
3. ANGO & other projects using ANGO platform share: 5%.
4. Number of users Number of participants: 34 million (calculated from per capita KPIs)
5. Number of transactions: 68 million (at least 2 transactions/user)
6. Economic impact: $33 billion (calculated from per capita KPIs).

In addition, the following impact can be expected.

• Revitalisation of the local economy: new tourist destinations and accommodation facilities will be created through the renovation of vacant houses, increasing the number of visitors from outside the area and stimulating local commercial and service activities.
• Increasing property values: the value of the renovated properties increases, which in turn contributes to the revitalisation of the local property market as a whole.
• Fostering technological innovation: the use of the Cardano blockchain will increase transparency in property management and transactions. This also represents a new use case for blockchain technology and opens up the possibility of its application in other industries.

These effects aim to demonstrate the potential of the Cardano blockchain through the success of the project and lead to its wider adoption.

> Building a cooperation structure

The ANGO project will deepen its engagement with the local community and other DAOs through the following cooperation structures

• Partnership with local communities and local DAOs: workshops and public discussions will be organized on a regular basis to enable local residents, DAOs and businesses to actively participate in the planning and implementation of the project. This will help develop plans based on local needs and promote community-based sustainable development.
• Technical support and education: we will provide educational programmes to engage local participants with Cardano's technology and provide enhanced technical support. This will reduce hurdles to the use of blockchain technology and promote the technology within the region.
• Collaboration with other Catalyst projects: we will collaborate with other Cardano community projects to share solutions to common challenges and mobilize resources to promote best practice globally.

Through these cooperation structures, the ANGO project will work closely with local communities and DAOs to support the development of the region as a whole and demonstrate the practical benefits of the Cardano blockchain.

What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

ANGO has already launched its services on Ethereum. So we believe we can do the same on Cardano.

ANGO has also been adopted as an official tool of the DAO Association of Japan and is one of the few projects in Japan, where limited liability company(LLC) - type DAOs are permitted, that can create many cases of projects utilizing both RWA and DAO.

ANGO will operate as a wholly-owned subsidiary of RECIKA and its personnel will be made up of RECIKA members.

RECIKA has been building solutions for the social use of NFTs, not only with ANGO, but also with other public companies such as UNICASK (<https://unicask.jp/>) and DigitalMe.

Our experience and past records ensure that the project is ready to be implemented with a high degree of reliability and transparency.

Thus, the team is very committed and the project has gained a great deal of credibility.

How does the cost of the project represent value for money for the Cardano ecosystem?

The ANGO project, which carries out renovation of vacant houses and local revitalisation efforts offers a high investment value to the Cardano ecosystem. Although the project involves costs, these costs are well justified and cost-effective for the following reasons

> (i) TVL (total value locked) increase.

Based on the following assumptions as described in the long term impact, we can expect TVL to rise by $55,120,000,000 ($55.1B).

• Number of properties: 424,000 units (see above)
• Property value: 20 million yen/unit
• Yen-dollar rate: 0.0065

This amount corresponds to approximately 650,000 times the investment amount.

Even if the number of properties is calculated for this MVP period (10 properties), a TVL increase of at least $1,300,000 (1.3 million) can be expected.

> (ii) Rise in the number of users.

If we assume a Long-Term, we can expect an increase of 33,920,000 users, as described in the expected impact portion.

Calculating that each user will do so at least two transactions (grant and use of accommodation NFTs), we can expect more than 60 million transactions.

> Other benefits can be expected to include.

• Driving technological innovation: a property management system powered by the Cardano blockchain will significantly increase transparency and efficiency, differentiating it from other blockchain platforms. This will trigger the adoption of Cardano technology in more industries.
• Building a sustainable local economy: attracting new commercial activity to the area through the rehabilitated vacant houses will have a direct economic impact on the local economy. The initiative is implemented with the support of the local community, thus promoting community involvement and support for the project.
• Expanding the ecosystem: by concretising property management as a Cardano use scenario and attracting new users and developers, the value and reach of the Cardano network is expanded.

In light of the above, the invested funds are expected to generate a high return on the expansion of the Cardano ecosystem and the funds are expected to be used effectively.
