The ruling Liberal Democratic Party plans to focus on four areas as it drafts proposals for the first-ever amendments to the postwar Constitution, including revisions to the war-renouncing Article 9 and changes to education policy, officials said Tuesday.

The LDP is working toward amending the supreme law after Prime Minister Shinzo Abe, who doubles as head of the party, made a controversial proposal for the revision of Article 9 last month, calling for a plan to be crafted by the end of the year.

Okiharu Yasuoka, the head of the party's constitutional reform panel, said Tuesday that a "concrete proposal" will be drawn up by the end of the year and sent to the Constitution Commissions in both houses of the Diet.
