Although the suburbs of numerous cities worldwide are shrinking, research on how to address suburban decline remains scarce. This paper explores participatory mapping in shrinking suburbs as a tool to articulate knowledge co-creation between local officials and communities to inform planning decisions. The paper argues that participatory planning...

This is the final report of the city-to-city collaboration between EU cities (including one from the UK) and Japanese cities under the International Urban and Regional Cooperation (IURC) Asia and Australasia. During 2021-2023, thirteen EU cities (including one UK city) from ten countries and ten Japanese cities participated in the project and...

Nationwide ageing and dramatic depopulation threaten the survival of many Japanese small-sized towns and villages. To address this challenge—which is not unique but that in Japan is compounded by uneven urbanization patterns and increasing ruptures within the socioeconomic order—the Government of Japan is encouraging municipalities to adopt a pro...

The transport sector is one of the main sources of global GHG emissions, of which road transport emissions are greatest. The decarbonisation of road transport requires systemic changes combined with technological interventions to optimise the use of transport modes. Given the diverse options for road transport decarbonisation due to differences in...

運輸部門は、世界における温室効果ガス（GHG）の主な排出源の1つであり、特に道路輸送の比率が高い。道路輸送の脱炭素化には、技術革新と社会変革を組み合わせ、輸送手段を最適化することが求められる。道路輸送の脱炭素化に際しては、技術の進捗状況や商業化のレベルが国や地域によって大きく異なるため、地域ごとのまちづくりや社会的課題の解決につながるような方策が求められる。運輸部門の脱炭素化は、広範な社会構造の変化につながり、気候危機といった深刻な問題に対する解決に貢献するとともに、豊かな交通社会を導く好機となりうる。

「川崎 脱炭素戦略の行方（下）住民の意識改革カギ：太陽光義務化や地域電力　モデル地区選び推進」 川崎市が環境都市に生まれ変わるには京浜工業地帯の脱炭素化だけでなく、住民の意識改革が欠かせない。市は太陽光パネルの設置義務化やモデル地区をつくることで、住民の行動変容を促そうとしている。 来年度施行へ 川崎市は7月末、環境審議会の脱炭素部会を開き、市内で新築する住宅への太陽光発電設備の設置義務化に向けた素案を示した。設置義務化の方針を表明している東京都の制度案を参考に、規模が大きい建物だけでなく、... （日本経済新聞の記事のページ：https://www.nikkei.com/article/DGKKZO64414520W2A910C2L72000/）...

Fernando Ortiz-Moya, urbanist working at the Institute for Global Environmental Strategies (IGES), explores the role of VLRs (Voluntary Local Review) in building better cities and what Tokyo is doing to achieve the Sustainable Development Goals.

As more countries witness depopulation, the expansion of High-Speed Rail (HSR) to reach shrinking cities in peripheral regions is renewing the debate on the effects of this infrastructure. This is the case in Japan, a country that continues to extend its highly developed HSR network hoping to curb regional decline. This paper investigates whether...

Japan’s severe population decline is seriously threatening the sustainability of many of the country’s municipalities. In a desperate run for survival, all levels of government have hurried to apply strategies aiming at stopping decay and the development of new infrastructure is met with particularly high expectations for new prosperity. That is...
