"Unfading Sun"

I watched a film,"Unfading Sun", which is the film based on Toyoko Yamazaki's 5-part novel.
This story is fiction but partly non-fiction.
I read this novel about 10 years ago. Most of her novels are non-ficton, so I like her novel.

In 1985, JAL Jumbo-jet air crash was happened in Osutaka-yama, Gunma prefecture and it killed more than 500 people.
This is the starting scene of the film.
This film shows why this accident was happened.
In this film, we can see Kokumin-Airline Company(which is the name of the airline company in the movie)neglected to emphasize the security and employees' work conditions.
The Labour Union advocated that the company should secure the safty flight and improve employee's work condition.
However, the company didn't change and improve them, and there was a huge conflict between employers and employees, which made it difficult to unite the company. The top management of Kokumin-Airline Company urged the main character, who was the leader of the Labour Union, to move to Karachi, Pakistan for 2 years, Teheran, Iran for the next 2years, and then Kenya for another 2 years to prevent the labour union uniting strongly and fighting against the employers.
I can see how the government and the company dealt with this air-crash accident and problem between employers and employees.

This movie took 3 and a half hours and there was 10-minite break in the middle of the film.
