Career
Jojima is the former head of Ajinomoto Workers' Union where he served for about 25 years and also, of Japan Food Industry Workers' Union Council. He then served as a council member of the Japan Productivity Center for Socio-Economic Development. He is a veteran lawmaker. He was first elected to the House of Representatives in 1996 as the number one candidate for the New Frontier Party in the multi-member Tokyo proportional representation block.

Following the dissolution of the New Frontier Party in 1997, Jojima became one of the founding members of the Democratic Party of Japan (DPJ) in 1998. At the 2000 general election he unsuccessfully contested the Tokyo 13th district but retained his seat in the PR block as the DPJ's #2 candidate. In the next election in 2003, he won the Tokyo 13th district, defeating incumbent Ichirō Kamoshita by 2,023 votes. In the 2005 election, Kamoshita regained the seat, defeating Jojima by more than 49,000 votes. This heavy defeat also meant that Jojima was unable to retain a seat in the Diet via the proportional representation block. Jojima returned to the Diet in the 2009 general election, this time contesting the Kanagawa 10th district.

Whilst in the Diet, Jojima served as the parliament affairs chief of the DPJ. He was also a member of committee on fundamental national policies.

At the December 2012 general election, Jojima suffered a defeat at the hands of Kazunori Tanaka, losing by more than 43,000 votes and failing to gain a seat via the Southern Kanto proportional representation block.
