Over the years that I have been researching revitalization in the Aso region in Kumamoto Prefecture one topic seemed to come up in almost every conversation – the efforts to make Aso a UNESCO World Heritage site. While the municipalities of the region have been working hard to get Aso added to the list of World Heritage sites, “surprisingly” – as noted in a blog by Aso City’s Michi no eki– it has not yet received this recognition (MICHINOEKI Aso 2021). I am biased, but anyone who has ever been to Aso must admit that it is a unique place. I still cannot get over the fact that a massive caldera is home to thousands of people. And there is of course the still very active Mount Aso sitting majestically in the middle of the caldera and lots of wonderful hot springs. The Aso region consists of seven municipalities: Aso City, Minamioguni, Oguni, Ubuyama, Takamori, Nishihara and Minamiaso. Only Aso City, Minamiaso and Takamori are located directly in the caldera but the whole region is part of the efforts to become a UNESCO World Heritage site as a volcanic region with a distinct cultural landscape (Kumamoto Prefecture 2020).

The cultural landscape mentioned here refers mainly to the grassland that covers large parts of the region. However, like so many rural areas in Japan, the region is struggling with a shrinking and aging population. For the cultural landscape this means that there are less people using and maintaining the grassland and that the forest has pushed forward reclaiming inch by inch. More than half of the area has already been lost over the last hundred years, and if nothing changes, most of the remaining grassland will disappear in the near future. The grassland of Aso has a long history, possibly dating back to the late-glacial period (Kawano et al. 2012). The protection of the grassland is therefore clearly connected to its significance as a unique ecosystem and the cultural heritage it represents. Being listed as a World Heritage site would offer protection and create new possibilities for financial support and investments. Another reason why countries might be interested in adding their sites to the list is the tourism boost they are likely to receive from the increased attention.

While working on a research project in the Kuma region, I met a researcher who supports Aso City’s efforts to get the Aso region on Japan’s Tentative List. Japan currently has 26 World Heritage sites, with four more sites on its Tentative List (MOFA 2024; Agency of Cultural Affairs n.d.). To be considered for a nomination, the site must first be included on the Tentative List that is prepared by each country. Even if a site gets on the list, it can still be a long way to the nomination. Two of the four sites on Japan’s Tentative List have been added in 1992. Nevertheless, becoming a UNESCO World Heritage site is the only way to secure the future of the grassland, this researcher told me. This would also include a boost in tourism. Tourism is deeply connected to revitalization efforts of rural areas. Because farming cannot sustain the income of the local population, tourism could be a way to stop the decline of Aso’s communities and attract new residents. Even if not so well known internationally, the Aso region has been a famous tourist destination in Japan for a long time. Still, local governments and local groups are struggling to make Aso a better place for tourists, hoping that this will make the region a better place for locals as well.

However, many people I spoke to, including government employees and people who depend on tourism for their livelihoods, were skeptical about the kind of tourism a nomination would bring. What Aso needs, I was told, are tourists who come to spend a whole week there. In other words, sustainable slow tourism. The locals voicing their concerns are not without reason. The examples of other World Heritage sites have shown that the status can come at a cost to nature and local communities. Think of the numerous news stories over the recent years about overtourism. Some places are completely overrun by tourists and need to find strategies to cope or reduce their numbers (Hall 2024). World Heritage sites are right in the middle of this trend. Paradoxically, the World Heritage status that should protect the cultural landscape could be a trigger for enormous stress on the local nature. Tourism needs infrastructure. Not only hotels, but roads, parking spaces, and toilets right up there on the mountain next to the observation deck, a government worker of Aso City explained to me with a troubled face. This means that some parts of the local nature might have to be sacrificed to meet the demands of economic interests. In recent years, semiconductor factories have been built in a town next to the Aso region, raising further questions about water use and environmental protection in the area.

The road to a nomination might still be very long for Aso. However, not only the region has a lot to gain from the status as a World Heritage site, because the cultural landscape is critically linked to the water supply far beyond the Aso area. I am curious to see how the UNESCO project in Aso will continue, what ways the proponents will find to allay the concerns of local communities, and whether being listed as a World Heritage site can really deliver the revitalization so many in the Aso region are hoping for.
