Tokushima 1st district (徳島県第1区) is a constituency of the House of Representatives in the Diet of Japan, located in Tokushima Prefecture on the island of Shikoku.

The district was created in the electoral reform of 1994. Previously, all of Tokushima prefecture had formed one SNTV multi-member constituency (5 representatives) since 1947. The new district was used in the 1996 election for the first time.

Liberal Democrat Mamoru Fukuyama, former six-term member and president of the Tokushima prefectural assembly and secretary-general of the LDP prefectural federation, defeated Democrat Yoshito Sengoku in the 2012 Representatives election by almost 20,000 votes. Sengoku, a candidate for the Democratic Party of Japan (DPJ) and its 1996 precursor had won the district five times after its creation. Sengoku, a lawyer and University of Tokyo drop-out, had previously represented the Tokushima At-large district between 1990 and 1993 for the Socialist Party of Japan.

Before redistricting in 2013, the district consisted of Tokushima city and the village of Sanagōchi in the Myōdō District and was among the least populated electoral districts in Japan. In the election of 2005 it had 214,763 constituents and its voters had the highest electoral weight throughout Japan. ^[2]
