An excrement analysis apparatus includes an inputter, a memory, a first analyzer, and a second analyzer. The inputter inputs imaging data captured by an image capture apparatus installed in such a way as to include, in a capturing range, an excretion range of excrement in a toilet bowl of a toilet. The memory temporarily holds the imaging data input by the inputter. The first analyzer analyzes first analysis target data being the imaging data input by the inputter, and outputs notification information to an observer who observes a user of the toilet. The second analyzer analyzes second analysis target data being the imaging data that is input by the inputter and temporarily held by the memory, and outputs detailed information indicating a content of excretion.
