Travel guidance system, travel guidance method, and computer program product

A travel guidance system comprises a navigation-route setting unit that sets a navigation route along which a movable body is guided and a guidance junction on the navigation route, a junction acquiring unit that acquires a position of a preceding junction that is located closer to a departure place of the navigation route than the guidance junction, a guidance setting unit that sets guidance on the guidance junction, and a junction guiding unit that provides guidance on the guidance junction on the basis of the guidance set by the guidance setting unit. The guidance setting unit sets the guidance such that the guidance includes a first phrase for specifying a positional relationship between the movable body and the preceding junction and a second phrase for specifying a positional relationship between the movable body and the guidance junction after the movable body has passed through the preceding junction.
