Japan's ruling Liberal Democratic Party has created a manual instructing its members how to avoid gaffes after several ministers were forced to resign over verbal blunders.
The party is aiming to tighten discipline ahead of the Upper House election this summer.
The manual cautions members about public speeches, saying words may be taken out of context by the media. It advises them to try to speak in short sentences.
It warns lawmakers to be careful when using "strong words." It says such expressions can make headlines and are potentially problematic.
It also says politicians should be careful when commenting on matters of historical understanding and political ideology.
The manual goes on to say members should be cautious when making comments on accidents and disasters that may lack consideration for those affected.
In April, the state minister of transport Ichiro Tsukada stepped down after making controversial comments about a road project.
In a speech about the project, Tsukada implied it was being done as a favor to Prime Minister Shinzo Abe and Deputy Prime Minister Taro Aso.
Also, Yoshitaka Sakurada, the minister in charge of the 2020 Tokyo Olympic and Paralympic Games, was forced to resign after he said a lawmaker he supports is more important than reconstruction from the 2011 earthquake and tsunami.
