Path display device and path display method

The operability of path management performed in units of apparatuses subdivided by disaggregation is improved.A path display apparatus 1 which displays a path configured for a plurality of optical network apparatuses subdivided by disaggregation includes a storage unit 10 that stores configuration information 11 indicating a section of each of the optical network apparatuses; a grouping unit 21 that identifies a high-speed port of a route apparatus (DIR: Direction) which is the optical network apparatus, and determines a first group to which optical network apparatuses divided by the identified high-speed port belong, based on the configuration information 11; and a display control unit 22 that displays, on a screen, a symbol of each of the optical network apparatuses, a symbol of the section, and a symbol of the first group.
