"love is the answer" - Elon Musk
I heard once that often times Japanese endings can be unsatisfying for western audiences because there isn't a sense of finality. According to the person I was talking to, Japanese stories are more concerned with the journey than they are with the ending.
I first read this story in high school on a recommendation from one of my favorite cousins. I loved it at the time because I was very into scifi and space in general. Since then, I've reread Planetes at least 4-5 times. Each time I was in a very different period of my life: undergrad, my first couple jobs, grad school after some uncertainty over my career, and then my current job. I often feel called back to reading this manga, during the uncertainties of a time of transition.
While I often feel a strong sense of nostalgia, different parts of the story stick out to me with every reading. Looking back, I can see that they correlate with different milestones in my life, not just in terms of school or career, but also in my relationships. I've made new friends and got closer to them, and I've drifted apart from other ones. I've fallen in love and experienced rejection. And, my extended family is now estranged due to some crazy drama between the older generation. As a result, I'm no longer in contact with the cousin that I looked up to and who showed me Planetes.
Planetes is a story about the journey of a young man as he faces different emotional and existential challenges in his life. His relationships with his friends, family, and significant other help him navigate this winding path, while at the same time they are going through their own journey. I personally appreciate this last chapter of Planetes as it shows how far Hachi has grown, while alluding to the fact that his journey is still not over, and that there are more lessons to learn and things to experience. I rarely reread or re-watch many things, but one day when I have kids, move across the country, or while experiencing loss, I expect to be back here revisiting this story in the future.
