Takanome is a service that visualizes the distribution and severity of litter on streets. 'Takanome for Automobiles' investigates wide areas using vehicles, while 'Takanome for Pedestrians' focuses on specific areas and provides more detailed results. Using such services, users can find out areas where litter tends to gather, and optimize their cleaning strategies to achieve the best results. This includes maximizing the efficiency of local cleaning activities, quantifying the effect of implementations, and etc..

Surveying the amount of litter around Totsuka station, the city obtained data necessary to maximize the placement of non-smoking areas
Measuring the intensity of litter in key Olympic venues, it became possible to improve the cleanliness of the 2021 games.
Research was conducted in partnership with a university team. This project allowed visualization of the distribution of litter around Kawasaki Station with a data-oriented and thorough perspective.
Started from a request from the local authority to conduct a litter distribution survey , the project was carried out under the cooperation of residents around Tsukamoto Station. Similar initiatives were also implemented in Higashiyodogawa Ward and Tennoji Ward.
With support from Professor IRIE Teruaki, Tokyo University of Agriculture, the distribution of litter around Tokorozawa station was investigated to explore the effects of smoking areas to litter distribution. It is found that after the removal of the smoking area, the amount of littering increased in the nearby park.
With support from Professor IRIE Teruaki, Tokyo University of Agriculture, the distribution of litter around Koiwa Station before and after the set-up of smoking areas was investigated. It is found that the number of litter around the smoking areas decreased after the set-up of smoking areas.
