PROBLEM TO BE SOLVED: To provide a biotoilet which can change urine to a useful liquid fertilizer by installing a conversion tank for converting urine-to-liquid fertilizer in place of a human waste tank in the pipework, is made more constructible and economical, and is made easy to maintain. SOLUTION: The biotoilet has a lavatory bowl which stirs dropped feces and saw dust and the like for fermentation and decomposition, a separating toilet bowl having the function of separating feces and urine, a rainwater hand washing device using rainwater for washing hands, and a conversion tank for converting urine-to-liquid fertilizer. The hand washing device by rainwater using rainwater for washing hands is connected to the lavatory bowl and the conversion tank for converting urine-to-liquid fertilizer by the pipework and the urine discharge portion of the separating toilet bowl is connected to the conversion tank by the pipework. The biotoilet is designed to make a liquid fertilizer by adjusting the water content in the lavatory bowl by a water content introduced from the hand washing device by rainwater and diluting urine introduced into the conversion tank with a water content introduced from the rainwater hand washing device by a factor of 2 to 5.
