Owase has a humid subtropical climate (Köppen climate classification Cfa). It has comfortable spring and autumn seasons, and warm winters with practically no snow. The warm Kuroshio Current makes its closest contact with the Japanese coast at Owase. Combined with the high mountains falling almost to the sea, this gives Owase an extremely heavy annual rainfall of 3,850 millimetres (150 in), which is the highest in the world at low altitudes in subtropical and warm temperate latitudes. Only certain parts of southern Chile, coastal British Columbia and the Adriatic Sea coast have as much rain at low elevations outside the tropics. Typhoons often pass Owase in summer.

Despite the excessive wetness of the climate, summers are no more uncomfortable or humid than in the rest of southern Japan. Humidity is marginally lower than in the cities close to the Seto Inland Sea or on the southern Sea of Japan.

Per Japanese census data, the population of Owase has decreased steadily over the past 50 years.

The area of present-day Owase was part of ancient Shima Province. It was transferred to Kii Province in 1582. During this time, large-scale forestry projects were begun. After the Meiji restoration, the area became part of Mie Prefecture. The town of Owase was established in April 1889, within Kitamuro District of Mie Prefecture, with the creation of the modern municipalities system.

The city of Owase was established in June 1954, by the merger of the town of Owase with the surrounding villages of Sugari and Kuki and the villages of Kitawauchi and Minamiwauchi, both from Minamimuro District.

Owase has a mayor-council form of government with a directly elected mayor and a unicameral city council of 10 members. Owase, collectively with the towns of Kihoku, contributes two members to the Mie Prefectural Assembly. In terms of national politics, the city is part of Mie 4th district of the lower house of the Diet of Japan.

Owase is mainly supported by its commercial fishery and forestry industries. Yellowtail, amberjack, Japanese horse mackerel, sauries, sea bream and bonito are among the fish landed at Owase. Japanese cypress and cryptomeria trees are found in abundance here in the mountains.

Owase has five public elementary schools and two public middle schools operated by the city government. One public high school is operated by the Mie Prefectural Department of Education. The prefecture operates one special education school for the handicapped.
