The father-of-three would talk to his children normally but said nothing to his wife.
Long-suffering Katayama Yumi chatted normally to her husband, but he would never respond.
And now the reason for his silence has been revealed - he was jealous of the attention his wife gave to their children.
The Japanese couple's 18-year-old son, Yoshiki, wrote to a TV show asking for help with his family's problem.
He told one of the presenters he has never heard his parents have a conversation.
His sisters, 21 and 25 years old, also said they had never heard their parents speak to each other.
He said: "My father doesn't talk to my mother but my mother talks normally to him."

His father, Otou, told the show: "When the kids were born my wife was very involved and busy in raising the kids.
"I was kind of... jealous. I was sulking about it.
"There's no going back now I guess."
He spoke to his wife for the first time in more than 20 years and told her: "Somehow it's been quite a while since we talked.
"I know you have endured a lot of hardship.
"I want you to know I'm grateful for everything. I also want to talk after this, I hope we can work together from here."
As they watched their parents have a brief conversation on a park bench the children cried with joy.
