Tokyo has been rebuilt inside Minecraft: is this the most ambitious digital city ever built?

From a simple video game sandbox to a platform for architectural and social experimentation, Minecraft has demonstrated over the years an astonishing ability to transcend the boundaries of its virtual world, positioning itself as an accessible tool that allows people to visualize, simulate, and reinterpret urban space with a freedom that is difficult to replicate elsewhere. 

In this groove of potentially limitless creativity also fits the recent project of Rikuma Mikuni, a young Japanese researcher who has reconstructed the entire Tokyo metropolitan area within the game. A feat that might seem, at first glance, to be yet another demonstration of tireless dedication by a member of a large community of enthusiasts, but instead reveals a far more interesting dynamic: the growing role of public data, and in this case three-dimensional urban data provided by the Japanese state, in contemporary cultural production. 

In fact, at the basis of the project carried out by Mikuni for the Minecraft Cup we find Plateau, one of the most advanced global experiments in digital twin urban provided by the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT): a platform of open source three-dimensional models that can be downloaded and reused by anyone, developed to support urban planning processes, climate disaster management and the implementation of smart cities.

Since 2020, PLATEAU Project has progressively collected and made accessible the three-dimensional models of numerous Japanese cities-integrating aerial surveys, topographical mapping, and administrative archives-until it has been configured as a true digital infrastructure. The result is a highly faithful representation of urban space: buildings, roads, bridges, land use and semantic metadata are encoded according to open standards such as CityGML and distributed under licenses that allow free reuse, even for commercial purposes. An information base that has extremely concrete applications: from seismic risk analysis to evacuation flow simulation, to support for sustainable mobility policies and, as in this case, unexpected practices such as that of Mikuni.

Through a specially developed conversion tool, the researcher has leveraged this open source data to convert Plateau's models into Minecraft blocks, rendering within the video game not only the geometry of streets and buildings, but also the complexity of the metropolis and its urban fabric, from the 23 central wards to the outlying areas and surrounding islands. Moreover, since Plateau provides datasets for each Japanese prefecture, Mikuni has already announced plans to convert other territories, with the long-term goal of reproducing the entire Japanese archipelago. 

The operation, when looked at from the video game perspective, is already surprising in itself; but when observed as a manifesto of the potential of an open urban digital twin - a meeting space between government data, individual creativity and the global digital community - it cannot but become a successful example of the contamination of public policy and digital culture, a further confirmation of how sharing public data can generate cultural, social and technological value far beyond their original function.
