Trade between Japan and Southeast Asia during the period from the Middle Ages to the early modern era was investigated using three historical documents (Rekidaihoan (歴代宝案, Precious Documents of Successive Generations), Tosen Yushutsunyuhinkiroku Suryoichiran (唐船輸出入品記録数量一覧, Quantity List of Imports and Exports Record by Tang Ships), Nagasaki no Toujinboueki (長崎の唐人貿易, Trade by Tang Merchants in Nagasaki)). Using HuTime, all the events recorded in those documents could be displayed along the same temporal axis. This made it possible to visualize what was imported into Japan during each period and how the political environment of the exporting countries affected regional commerce.

Similar utilization examples

• Research into the prefectural histories of Yunnan Province, China.

This study investigated how the prefectural government and public reacted to environmental changes and disasters in the Lake Biwa area of Shiga Prefecture, Japan. Using HuTime, the researcher visualized monitoring data related to water levels and quality, while displaying the proceedings of the Shiga Prefectural Assembly on the same temporal axis, even though these were different types of data. (For example, numerical and character data could be displayed in line charts and chronological tables, respectively.) This visualization enabled investigators to compare natural events in the lake to the assembly's reactions. HuTime was also used to identify events related to topics extracted from four chronological tables created by different organization. Those extracted events were then recombined into a new topic-based chronological table using HuTime.

• Chronological table about environmental history (Research Institute for Humanity and Nature, Research Project "A New Cultural and Historical Exploration into Human-Nature Relationships in the Japanese Archipelago")

During the course of an investigation by Japan's Research Institute for Humanity and Nature entitled "Environmental Change and Infectious Disease in Tropical Asia" HuTime was used to collect research documents about schistosomiasis (a parasitic disease) in China. The program allowed researchers to visualize the described periods of each collected document, which then helped researchers locate previously uncollected documents and determine the most significant periods related to the subject.
