Vivace City is a flashy entertainment destination located in south-east Urobos at the intersection of Route 11 and Route 12. The city is entirely underground, requiring an elevator to get into. It features multiple casinos and the Vivace Gym, the fourth gym of the Urobos League.
There are three major casinos in Upper Vivace: the Brass Palace, the Ostina Casino, and the Back Beat. The player can partake in several different games at the casinos and try to win prizes such as items or Pokémon.
The Train Station is located in the northeastern part of the city. The player can board a train here to travel to other cities in Urobos.
The design of Vivace City is based on many nightlife and festival scenes in South America, such as the many casinos of Peru and the holiday of Carnaval, and also draws inspiration from Las Vegas. The blue glow of Lumishroom in Lower Vivace was an early feature in the development of Vivace City. The glow is reminiscent of glowworm caves as well as the neon lights of cities such as Las Vegas.
In Vivace City's lower area, one of the graffiti found on the walls reads "BORDA". This refers to the Borda count, a method of tabulating ranked votes which is used by the development team to make decisions after running surveys.
Vivace is a musical term indicating a movement that is in a lively mood, and typical with a fast tempo. It is usually found at the start of a new phrase during the piece. This follows the theme of locations in Urobos being named with musical terms, and relates to the wild and excited atmosphere of the city.
