Not Amazon or kindle, but the first 50 (!) chapters of Space Brothers (宇宙兄弟) are available to read for free online now:
It’s a great manga, so don’t miss out on this.
The first free volumes are free on Amazon, so I would assume that’s those chapters.
Anyway, A Silent Voice Volume 1 is free at the moment!
It’s been a bit since something on my wishlist has been free!
Thank you for this thread! 
I’d never heard of キノの旅, but a manga about a girl and her (talking?!) bike… Downloaded!
Her bike looks kind of like mine 
There was also previously a book club, but I believe that was for the novels while this sale is for the manga.
Oh thank you for the heads up! That will definitely be helpful once I’m good enough to start reading intermediate club picks! (I’m still at a manga or kids book level for now
)
The first five volumes of Silver Diamond are currently free on Amazon Japan:
Vol 1, Vol 2, Vol 3, Vol 4, Vol 5
This series holds a special place in my heart; it’s the one that got me learning Japanese! Quick summary from Amazon:
“Rakan, an orphan with no knowledge of his past, meets Chigusa, a mysterious man who tells him he is a Sanome, someone who can control how plants grow, as they battle against assassins and monsters from another world.”
The manga’s got a great sense of humor with a plot that slowly builds into a very satisfying conclusion. The mangaka’s the same as the one who wrote 氷の魔物の物語, for any who’ve read that.
Thanks for that great tip! I used to have the Skybooks app for public property book titles in Japanese, but they stopped updating the app (as far as I can tell).

Attack on Titan, vols 1-3: vol 1, vol 2, vol 3

Knights of Sidonia, vol 1-3: vol 1, vol 2, vol 3
It looks like a good chunk of the Crayon Shin-chan manga is on sale for ¥30 apiece as well; here’s a link to the first volume for those interested. You can find the rest of the books by scrolling down the page a bit.

Thank you, all of you, for the links!
First two volumes of 徒然チルドレン are free on Amazon right now.
First three volumes of 甘々と稲妻 are free right now.
Thanks for the heads up!
Regarding Amazon free kindle books, do you know if they are like a purchase or someday they will vanish from your Kindle when you synchronize?
I am almost certain that I watched all of the anime episodes of 甘々と稲妻 but I cannot remember much… I just have this vague feeling I loved it. I wonder if this is a sign I’m getting too old…
Thank you!
I’ve only read the manga, and definitely loved it. Been meaning to watch the anime. Basic plot summary, to jog your memory: widowed father teams up with lonely mother-is-always-at-work teenager to cook meals for his young daughter.
