Kagoshima's "Inside" and "Outside" Connected by a "Satsuma BASE" Platform for Related Population, Officially Launching Activities!

Satsuma BASE: A Related Population Platform Connecting Kagoshima's Inside and Outside

Satsuma BASE (Representative: Takahiro Shinchi), a platform for related population designed to circulate people and resources between the inside and outside of Kagoshima, is officially launching its business activities with the release of its official website (https://satsumabase.jp).

Satsuma BASE is a project aiming to create a "related population economic zone of 10 billion yen annually in Kagoshima" by connecting dormant values, people, money, and sentiments within the region and transforming them into a continuous economic cycle.

Amidst declining population, aging demographics, and shrinking regional economies, it is becoming difficult to sustain Kagoshima's future solely on its internal population and consumption. Therefore, it is essential to increase the number of people who continuously engage with Kagoshima from the outside, creating a system where people, money, jobs, and support circulate.

Satsuma BASE will foster diverse forms of engagement such as learning about Kagoshima, visiting, purchasing, supporting, creating jobs, and promoting it, thereby advancing the construction of a related population economic zone that continuously attracts investment for Kagoshima's future.

Background of the Launch

Creating a System for People, Money, and Sentiments to Circulate from Outside Kagoshima in an Era of Population Decline

As of June 1, Reiwa 8 (2026), Kagoshima Prefecture's population is approximately 1.5 million, a decrease of about 17,000 from the same month of the previous year.

A decrease in population is not just a reduction in numbers. It means less money spent in the region, fewer people to carry out tasks, declining tax revenue, and a weakening foundation supporting local activities and public services.

Assuming an annual consumption of approximately 1.35 million yen per resident, a population decrease of about 17,000 people corresponds to a loss of approximately 23 billion yen in annual purchasing power from the region.

Furthermore, while Kagoshima Prefecture's tourism consumption in Reiwa 6 (2024) showed a recovery trend at 236.8 billion yen, it remains about 48.8 billion yen lower than in Reiwa 1 (2019), before the COVID-19 pandemic.

If we continue to rely solely on the internal population and consumption, local businesses and operators will see reduced sales, fewer job and employment options, and this will impact the quality of life and sense of security for the people living in Kagoshima.

And this is not just a problem for Kagoshima. If regions merely compete for a shrinking domestic market, Japan as a whole will gradually weaken. It is essential to circulate people and value between the inside and outside of regions, creating a system where money, jobs, opportunities, and support continuously flow in from outside the region.

Kagoshima Today: Population Decline and Shrinking Regional Economy

The "related population" that Satsuma BASE aims for is not just people who visit once as tourists.

It refers to people who learn about Kagoshima, visit, buy its products, support it, create jobs, and promote it. This includes people who buy Kagoshima's products, make hometown tax donations, participate in events and experiences, support regional projects, work with local businesses, and spread Kagoshima's appeal both domestically and internationally. Each of these continuous engagements brings new money, jobs, opportunities, and support from outside Kagoshima.

The "related population economic zone of 10 billion yen annually" advocated by Satsuma BASE can be achieved if 100,000 people engage with Kagoshima by 100,000 yen each annually.

Visiting Kagoshima once a year. Buying Kagoshima's specialty products. Making hometown tax donations. Participating in events. Supporting regional projects. Commissioning work from local businesses. People from overseas purchasing Kagoshima's products or experiences.

If these engagements are accumulated, an annual economic circulation of 100,000 yen per person is not an unrealistic figure.

We will compensate for the loss of regional consumption due to population decline with continuous engagement from outside the region, and further transform it into investment for Kagoshima's future.

This is why Satsuma BASE aims to "create a related population economic zone of 10 billion yen annually in Kagoshima."

What Satsuma BASE Aims For

Shedding Light on Dormant Value and Circulating it for the Region's Future

Kagoshima possesses rich nature, food, culture, history, traditions, and attractive people who support the region.

On the other hand, much of this value is not yet fully known. What may seem ordinary to those within the region can be a great attraction from the outside. There is also value in one's hometown that is only realized after leaving it. Possibilities may only become apparent through encounters with people from outside the region.

Satsuma BASE will shed light on these values that emerge at the intersection of the inside and outside of the region, opening up ways for people, both domestically and internationally, to engage with Kagoshima.

What we aim for is not mere tourism promotion.

It is to foster continuous relationships beyond one-time tourism, exchanges, support, work, investment, and promotion. And to connect the circulation of people, money, and sentiments born from these relationships to the region's future.

Satsuma BASE will create a related population platform for leaving a hometown that future generations, our children and grandchildren, can be proud of, together with those who do not give up on Kagoshima's future.

Comment (Aiko Kanehira, Representative Director CEO)

It is deeply regrettable to witness the decline that Japan and Kagoshima are currently facing. That is precisely why my soul deeply resonates with Shinchi-san's vision and passionate activities. I am convinced that this initiative, which fosters warm connections between people, will become a model that all regional areas in Japan should aim for. To invigorate Japan, we start from my beloved hometown, Kagoshima. Not as mere supporters, but as FAMILY with shared souls. To pass on the charm that future generations can be proud of, we will wholeheartedly co-create a warm, blood-flowing future with love and passionate warmth.

Comment from Satsuma BASE Representative (Takahiro Shinchi)

"I want to leave Kagoshima, the place where I was born and raised, as a place that my children, grandchildren, and future generations can be proud of." Satsuma BASE began with that sentiment.

Kagoshima has abundant nature, food, culture, history, and attractive people who live rooted in the region. However, in the face of population decline, aging, outflow of talent to urban areas, and changes in the global economy, it is not easy to preserve the region's richness.

On the other hand, many values in Kagoshima remain undiscovered.

When I left Kagoshima at the age of 24, I realized the charm of my hometown only after leaving, and discovered values that I could only see through encounters with people from outside the region. Satsuma BASE will shed light on these values that emerge at the intersection of the inside and outside of the region, deliver them to people both domestically and internationally, and circulate the resulting interest, consumption, support, jobs, and investments for the region's future.

What we aim for is not mere tourism promotion. It is to increase the number of companions who continuously engage with Kagoshima and "create a related population economic zone of 10 billion yen annually in Kagoshima." We will create a new circulation of people and economy, and build a future where the people living in Kagoshima can continue to spend their days with smiles.

Takahiro Shinchi, Representative of Satsuma BASE

Future Outlook

Satsuma BASE will increase the "related population" that continuously engages with Kagoshima by combining real-life interactions with digital mechanisms.

In the future, we will expand initiatives to circulate Kagoshima's value both inside and outside the region through local events, exchange programs, digital membership cards, regional information dissemination, and collaboration with co-creation partners.

We aim to become a regional revitalization model for Japan, a related population platform originating from Kagoshima, while recruiting companions, both individuals and corporations, who resonate with Satsuma BASE's vision.

We will compensate for the loss of regional consumption due to population decline with continuous engagement from outside the region, and further transform it into investment for Kagoshima's future.
