The government is considering revising the Civil Code to lower the age of majority from 20 to 18, which would allow some of today's teens to make their own legal decisions without parental consent, government sources said Thursday.

The revision would affect about 200 laws that have provisions concerning legal restrictions for minors, a senior Justice Ministry official said.

The government plans to submit a bill to revise the Civil Code and 20 to 30 of the 200 laws during an ordinary Diet session that opens in January, the official told The Japan Times.
