From September 2 to 5, the international conference “3D GeoInfo & Smart Data Smart Cities 2025” (the 20th International 3D GeoInfo Conference 2025 and the 9th International Smart Data and Smart Cities Conference) was held at the Kashiwa Campus, the University of Tokyo, co-hosted with the Ministry of Land, Infrastructure, Transport and Tourism (MLIT, Japan).
The event far exceeded our initial expectations, attracting more than 200 participants from around 20 countries —primarily from Europe and North America— and provided a valuable opportunity for active discussions and networking.
Despite the extreme heat, the entire program was completed as scheduled. Many participants commented that “the Kashiwa Campus offered a quiet and nature-rich environment, conveniently located near the hotel, which allowed us to concentrate on intensive discussions with the same group throughout the week.” We are truly delighted to receive such positive feedback.
We would like to express our heartfelt gratitude to all who joined us. Looking ahead, we hope to further strengthen collaboration with colleagues both in Japan and abroad, and to contribute to both academia and society.
About the 3D GeoInfo & SDSC
The 3D GeoInfo series, launched in 2006, is a leading international conference on 3D city models and geospatial information science. The Smart Data Smart Cities (SDSC) conference has been held since 2016 with a focus on urban data science. While previous editions have taken place in Europe, North America, and Australia, the 2025 meeting marked the very first time it was hosted in Japan. The conference brings together experts in urban planning, architecture, geoinformatics, disaster management, and computer science to advance global contributions to sustainable cities through smart city technologies and digital twins. The next edition (2026) will be held in Sofia, Bulgaria.

9月2日から5日にかけて、東京大学柏キャンパスにて、国土交通省との共催で国際会議「3D GeoInfo & Smart Data Smart Cities 2025」（the 20th International 3D GeoInfo Conference 2025 and the 9th International Smart Data and Smart Cities Conference）を開催しました。当初の想定を大きく上回り、欧米を中心に約20カ国から200名以上の方々にご参加いただき、活発な議論と交流が行われました。
酷暑の中ではありましたが、予定通り全プログラムを終えることができました。また、参加者からは「柏キャンパスは静かで自然に恵まれ、宿泊先のホテルからも近く、一週間を通じて同じメンバーで濃密な議論に集中できたのが大変良かった」との声も多く寄せられ、非常に嬉しく感じています。
ご参加いただいた皆様に心より御礼申し上げます。今後も国内外の皆様との連携を深め、学術と社会の双方に貢献できるよう取り組んでいきたいと考えております。
【3D GeoInfo & SDSCについて】
3D GeoInfoは2006年に始まった都市3Dモデル・空間情報科学分野の国際会議で、SDSCは2016年より都市データサイエンスに特化して開催されています。これまで欧州や北米、豪州などで開かれてきましたが、日本での開催は今回が初めてです。都市計画、建築、地理情報科学、防災、情報工学などの専門家が集い、スマートシティやデジタルツインを通じて持続可能社会への貢献を目指しています。次回（2026年）はブルガリア・ソフィアにて開催予定です。
