Abstract
This paper illustrates how, among Chinese migrants in Japan, the notion of belonging is constructed and modified by their use of digital technology, by presenting digital technologies as a continuum of physical and digitized life experiences.
Drawing on interviews with 55 Chinese migrants in Japan, this paper argues that Chinese migrants are increasingly engaged in digital spaces that combine the online and offline and permit their presence at a transnational scale, through a collectively imagined 'Chinese' identity. However, because of the influence of physical spaces on Chinese migrants' transnational, diasporic experiences, this transnational engagement does not lead to the construction of a transnational or a relatively static nation-state sense of belonging. Instead, for Chinese migrants in Japan, the notion of belonging can be based on the situation and context, and it can switch between the home and host countries.

Shrinking cities have become increasingly prevalent worldwide due to various factors, which pose serious challenges to affected areas in terms of population decline, economic decline, and spatial deterioration. While existing research studies have focused on identifying shrinking cities, there is a need for global projections to mitigate uncertainties in their growth trajectories. Spatially explicit population grids offer a new approach to identifying potentially shrinking cities with sufficient spatial resolution. By utilizing a global gridded population dataset from 2020 to 2100 under the SSP2 (Middle of the Road) scenario, we produce a global projection map for future shrinking cities. Among the total 19,024 natural cities, 9682 cities (50.9%) will face population decline and 1751 cities (9.2%) may lose more than half population by 2100. Cities in East Asia and East Europe may face serious population decline.
