Yuichiro Tamaki, leader of the Democratic Party of Japan, announced on the 5th that he plans to participate in the Social Security National Conference, which focuses on discussions around reducing consumption tax on food and implementing tax credit allowances. The National Council was created by the ruling government and initially included only the opposition team 'Mirai.' However, there is now a positive response from the Center-Right Reform Alliance and Komeito, who are also showing interest in joining the discussions. In a party meeting on the same day, Tamaki mentioned that he is willing to participate as the organizers have agreed to meet certain requests regarding the transparency of the meeting and the selection of knowledgeable persons for the discussions. The Democratic Party is advocating for a general reduction of consumption tax to 5%, arguing against the idea of making the consumption tax on food zero, citing potential negative effects from various angles based on data and evidence. They intend to firmly express these views during the meetings beginning next week with practitioners. The first meeting of the National Conference was held on February 26, with requests made for the Center-Right, Democratic Party, and The Mirai party to participate. However, both the Center-Right and Democratic Party refrained from participating initially as a result of their objections to the inclusion of only certain parties and how the meetings would be managed. As of April 4, the ruling parties have reached out to invite other parties, such as the Constitutional Democratic Party and Komeito, to join in the discussions ahead. The outcome of this conference may significantly influence future tax policies and social security discussions in Japan.
