Ruling Liberal Democratic Party lawmakers tasked with drawing up proposed constitutional amendments approved a plan Tuesday that does not include a guarantee to make all education free.

The LDP's decision comes as the party continues to debate proposed revisions, with an aim toward presenting a final bill to the regular Diet session next spring. That prospect looks increasingly difficult given the complexity of the debate and concern from other party members about rushing deliberations, as well as reluctance from coalition partner Komeito.

Some Komeito members have expressed concern over amending the Constitution to establish provisions for free education, saying that the issue can be dealt with through normal parliamentary procedures.
