On my way out of town to walk upriver to Bungo Ono I passed through one of Oita's covered arcades.
This one had a huge model of what I believe is a Portuguese sailing ship. commemorating the city's historical connection with Portuguese trade as well as Christianity.
Arcades are a pleasant way to walk across a city without having to deal with traffic too much
Though during the daytime they can be crowded with pedestrians and bicycles
