How Much Is Your Life Worth?

I sold my life for ten thousand yen per year. (Jumyou wo Kaitotte Moratta. Ichinen ni Tsuki, Ichimanen de. / 寿命を買い取ってもらった。一年につき、一万円で。) is a manga about a 20-year-old who sold the remaining 30 years of his life for a total of ¥300,000.

For anyone wondering, that’s $1,913.76 as of June 7, 2024.

After selling off those 30 years, Kusunoki was left with a whopping 3 months to live. So, was it the transaction worth it? Arguably, yes. The reason for that is that the valuation of Kusunoki’s lifespan was based on the quality of the rest of his life.

Basically, if Kusunoki didn’t take the money, the next 30 years of his life would have been miserable. He would have been alone and never achieved anything of note. And as we find out a bit later in the series, he also would have been severely crippled at some point.

Looking at it that way, it may seem better to be here for a good time, not a long time. However, less than $2,000 doesn’t really afford much. So, would you have taken this deal if you were barely scraping by? I can’t say I would have.

The amount of money I received would have to fix every single one of my problems for my remaining 3 months. $2,000 isn’t going to cut it.

But how much would be worth the trade? Let’s say you’re in Kusunoki’s situation and have 30 years and 3 months left to live. How much money would you need to receive in order to sell 30 years of your remaining life?

I don’t think there’s any price that would make that trade worth it to me. Even if it was an infinite amount of money, I only get it for 3 months.

The Invisible Girl

The whole question about how much a life is worth is interesting. But what’s more interesting is the system that this company(?) that deals in lifespans has set up. Once you have less than a year of life remaining, they assign a supervisor to your case.

This supervisor stays with you 24/7 until you have only three days remaining. At that point, they leave, and you can do whatever you want. But why are they supervising people like this? Allegedly, it’s to make sure these people don’t go crazy and commit heinous crimes once they realize their life is ending.

The reason given for the final 3 days being unsupervised is that, at that point, people tend to give up. They accept their imminent death and aren’t much of a threat to anyone else.

So, who are these supervisors? Most of them are people who sold their “time” to the company. You can sell your lifespan, as Kusunoki did. You can sell your time and become a supervisor. Or you can sell your health. Also, we know you can buy these things, too. That’s not explored too much, but I guess a billionaire could be immortal.

Something else about these supervisors is that the only person who can see them is the person they’re observing. Miyagi is Kusunoki’s supervisor, so only he can see her. If he talks to her in public, it looks like he’s talking to himself to anyone who sees him.

This was, by far, the most interesting part of the manga. Is Miyagi actually real? Is she a figment of Kusunoki’s imagination? If she’s not real, is Kusunoki actually going to die at the end of his 3 months? There are a lot of questions that need answers.

Three Days of Happiness

Did you know that the I sold my life for ten thousand yen per year. manga is an adaptation of a novel called Three Days of Happiness? I’m not really sure why they author changed the name for the manga version. But it could have something to do with Three Days of Happiness being a bit of a spoiler.

So, let’s spoil it.

Miyagi is a supervisor because she had to pay a debt her mother owed, and she chose to do so with her time. Then, as she was supervising Kusunoki, she fell in love with him (and he fell in love with her). Of course, the problem with that is that, by the time this happens, Kusunoki has about 2 months left to live.

That’s not much time for the two of them to spend together. So, Kusunoki comes up with a plan. He’s going to make his remaining life worth something and then sell it off to pay for Miyagi’s debt.

This plan goes about as well as it could have. Kusunoki can’t pay off all 30 years of Miyagi’s debt. But he manages to pay off about 27 years’ worth. What Kusunoki didn’t expect is that Miyagi learned about his plan from another supervisor.

Miyagi didn’t want Kusunoki to sell his remaining life. She wanted to spend as much time with him as possible, and if he pays off her debt, his life ends sooner. So, once she finds out what Kusunoki did, she does the stupidest thing possible.

Miyagi also sells her remaining lifespan. It’s kind of like a Romeo and Juliet situation. She decides she doesn’t want to live without Kusunoki. So, the two of them only have their final three days to spend together — their three days of happiness.

Final Thoughts

I sold my life for ten thousand yen per year. is a 9/10 manga. I knew it was highly rated before I began reading it. But I didn’t think I’d actually like it as much as I did. It’s a great drama and romance manga that I recommend to anyone who likes those genres.
