Winner of the 8th WOWOW screenplay grand prix 2016 according to jadefrost, Futabasou no Yujin is about a couple played by Ichihara Hayato and Usuda Asami who move into a semi detached house.
They becomes friends with their neighbour who lives next door by herself while her husband is away and Hayato starts seeing a ghost in the house.
Hayato and the ghost are unable to speak with each other but can communicate by signing and writing so Japanese reading is required to watch this but not necessarily.
Hayato quits his job and Asami is promoted and given a lot of work thus putting pressure on their relationship.
Whoever Usuda Asami's agent is, he/she does a good job of getting her good roles.
I won't spoil the story but its kind of a typical ghost story but I like the execution, especially with the acting and the ghost bits are fun to watch and the 2 hours flew by very fast.
Futabasou no Yujin straddles the line between very watchable and must watch and I do not hesitate to recommend it. You can easily find it by googling Futabasou no Yujin SP2016 720p HDTV x265-ER. Very watchable and deserves to be subbed.
