Among other waste issues, the disposal of human waste has historically been one of the most serious challenges for major cities. The historical literature suggests that Japan’s urban society took a unique approach to management of human waste. Throughout Japan’s early modern period, human waste in the city was purchased by farmers living on the urban fringe and was used as an agricultural fertilizer. Using this “night soil,” villages supplied fresh agricultural produce to the urban market.

Night soil collecting was practiced to different extents wherever urbanization developed. For example, Japan relied on human waste as fertilizer to the point it became a profitable business, while in most Western countries it was considered a necessary evil. What is the reason behind such different attitudes? In this paper, I apply David Inglis’ theory of a mode of excretion to premodern Japanese context in order to shed light on this phenomenon. First, informed by Mary Douglas, I propose slight alternations to the original theoretical framework of a mode of excretion so it emphasizes considerations of excreta in a culture’s cosmology. Next, I examine scatological content in the oldest chronicle of Japan: Kojiki. Based on the analysis, I conclude the Japanese traditional notion of defecation is non-binary—it includes both positive and negative understandings of excrement. Most importantly, the notion lacks moral stigmatization; excrement is not kegare. Then, I characterize how defecation was practiced. Contrary to present norms, it was conducted relatively out in the open, without strict regularization. I argue it was because the notion was not stigmatized, thus there was no need to be particularly embarrassed about the body’s excretory capacities. Finally, I conclude the holistic approach to the notion and practice of defecation in Japan’s traditional fecal habitus is the reason why human waste could be viewed as productive and not merely an object of disgust. Thus, because of this cultural encoding, traditional means of excretory disposal in Japan relied on night soil collection.

Providing safe excreta disposal following disasters is important for disease prevention and the safety and dignity of the affected population. This is challenging because every emergency varies due to the nature of the disaster, local conditions and the characteristics of the affected population. This paper investigates the impact of the 2006 Java earthquake on excreta disposal needs and the response to those needs. Relevant documents were retrieved from the ReliefWeb database, complemented by a literature search. The case study highlights gaps in rapidly providing latrines on a large scale. Three months after the disaster, only 57% of the latrines targeted had been provided. One way to address this problem is to better understand the factors affecting excreta disposal needs and response, allowing appropriate solutions to be identified more effectively.

The importance of a water supply and sewage treatment for urban sanitation is recognized in the modern world. Their contributions to public health have not, however, been well demonstrated by historical data, especially in Asian cities. In this research, we focused on the Asian cities of Tokyo and Singapore, which both developed significantly in the 20th century. We analysed their development processes statistically to determine what the key elements for the protection of urban sanitation have been. Although both cities constructed modern water supply systems at almost same time (Tokyo in 1898 and Singapore in 1878), and similarly modern wastewater treatment systems (Tokyo in 1922 and Singapore in 1913), the prevalence of water-borne diseases in Tokyo was more serious than it was in Singapore, in spite of Singapore's high infant mortality rate. The main reason for this was the differences in the systems of night-soil transport. We found that the water supply system in itself was...
