The International Cartographic Association (ICA) mourns the passing of Dr. Tositomo Kanakubo, a distinguished Japanese cartographer, long-standing contributor to the international cartographic community, former ICA Vice-President and ICA Honorary Fellow. Dr Kanakubo passed away on 28 August 2026, following a brief, severe illness.
Dr. Kanakubo worked at the Geospatial Information Authority of Japan from 1953 to 1986, serving as its Director-General from 1984 to 1986. He was closely associated with the ICA over many decades and made an important contribution particularly to the development of theoretical cartography. From 1995 to 1999, he chaired the ICA Commission on Theoretical Fields and Definition in Cartography. He subsequently continued his involvement as a member of the ICA Commission on Theoretical Cartography from 1999 until 2011. At the same time, he served the Association as ICA Vice-President from 1991 to 1999 and was elected an ICA Honorary Fellow in 1999.
His engagement with ICA was characterised not only by scientific contributions but also by sustained international collaboration, bringing together scholars interested in the conceptual and theoretical foundations of cartography. He also helped strengthen the links between ICA and the Japanese cartographic community.
The history of ICA is built not only through conferences, publications and commissions, but through people who establish intellectual and personal connections across countries and generations. Tositomo Kanakubo was one of those people. His long engagement with theoretical cartography, his commitment to international scientific exchange and his service to ICA made him a respected member of our community.
The International Cartographic Association extends its sincere condolences to Tositomo Kanakubo’s family, friends, colleagues and the cartographic community in Japan. We remember with gratitude his contribution to cartography and his many years of dedicated service to ICA.
Tositomo Kanakubo will be remembered as a scholar, colleague and friend whose work helped strengthen the theoretical foundations and international character of cartography.
