Support from the opposition Democratic Party for the People is expected to allow a bill criminalizing vandalism of Japan's national flag to pass the upper house of the Diet.
The ruling bloc lacks a majority in the upper house. Backing from the Democratic Party for the People, led by Yuichiro Tamaki, provides the necessary support for passage.
The bill targets acts against the Hinomaru flag. It comes amid discussions on social media and human rights issues.
Passage is anticipated following the opposition's decision as reported on June 16.
