The construction of the database and map systems, which provide basic information for evaluations and countermeasures of the Fukushima nuclear accident, are explained. Fukushima Daiichi Nuclear Power Plant had been damaged and spread out radioactive materials around there on March 2011. There are still a lot of requests to know the distribution of radioactive material from government, local government, residents, and/or researchers. In order to meet those requests, we developed two systems to provide those data to the public. One of the systems is a database system which is designed to provide quantitative data for detailed analysis. Another is a map system which provides intuitive images for the qualitative estimation.
