Unconventional Weapons in SAKAMOTO DAYS | Netflix Anime

Once the greatest hitman of all, Taro Sakamoto retired in the name of love. But when his past catches up, he must fight to protect his beloved family.

0:39 the irony of this guy saying "cast iron technique" only to get taken out by what is possibly a cast iron pan

[johanstenfelt]

I have not watched this, but i like this guy already.

[GeekX]

It's amazing how Sakamoto hasn't lost his fighting skills and can still lose weight. He's like Terry Silver from Cobra Kai.

[neihljohn]

Seriously, Mr. Sakamoto really knows how to weaponize/use as guard on everything, even the most unlikely and simplest of items. Mad respect to the man.

Sakamoto hits a ping pong ball, which, on average, has a mass of a measly 2.7 g or 0.0027 kg
This same ping pong ball is able to *launch someone* off of their feet into the air, which, given mass vs mass, is a lot of speed.
Assuming the man is an average Japanese man and therefore weighs about 69.5 kg, which I will lowball to 65 kg for the sake of illustrating this comment's absurdity.
The man travels approximately his entire height in 4 frames, or about of a second given 15 fps, is... already worrying.
Lowballing the speed the man flew horizontally to be about twice his height in 18 frames, or 1.2 seconds, given that some of those frames were slowed down, is realistic by animation causing him to fly about his own height one time, then do it again on the way down.
Estimating the man's height as the average Japanese male height of 1.7 meters, the man flew 1.7 meters up in 0.267 of a second and 3.5 meters horizontally in about 18 frames.
Now, I highly doubt this is an elastic collision as the unfortunate victim flew 3.4 meters from a directly horizontal collision, so instead of the kinetic energy equation, which will be saved for later, we'll use the momentum equation which always gets conserved during any collision.
Momentum is equal to Mass multiplied by Velocity (mv, ) and is always conserved in these collisions, so by this equation,
(0.0027kg)(unknown ping pong ball velocity) = (65kg)(figurable victim's velocity)
Horizontal and Vertical Momentum are independent of each other, so we'll have to calculate them in two separate equations and add them together.
(0.0027kg)(unknown ping pong ball velocity) = (65kg)(unfortunate victim's horizontal velocity)
(0.0027kg)(unknown ping pong ball velocity) = (65kg)(how is this victim alive vertical velocity)
Assuming constant velocity because the ping pong ball, the only source of motion, is only active for about 1 frame, allows us to input velocity = distance/time as this won't include air resistance by the sake of I have no idea what his projectile coefficient would be.
Therefore,
(0.0027kg)(unknown ping pong ball velocity) = (65kg)(1.7m/0.267s)
(0.0027kg)(unknown ping pong ball velocity) = (65kg)(3.5m/1.2s)
moving the ping pong ball mass gives
ping pong horizontal velocity = 65kg*1.7m/(0.267s*0.0027kg) = *153280.6214 m/s*
ping pong vertical velocity = 65kg*3.5m/(1.2s*0.0027kg) = *6829.87654m/s*
which means, by the Pythagorean theorem, means:
Ping Pong average velocity = sqrt(horizontal^2 + vertical^2) = *167, 947.3437 m/s*

*OH BUT IT GETS DEEPER*

Because the victim was also rotated about 90 degrees in those same first 4 frames, we can start using the *angular momentum* as well.
Similar to linear momentum, angular momentum has a definition of
P=MV
not too complicated, but V is now "radial velocity" and therefore is equal to radius*linear velocity (which we don't have).
however...
Assuming Sakamoto's unfortunate enemy got rotated about his height-based center, means that the "radius" would be half his height, or 0.7 meters.
His Mass is still the same 65 kilogram estimation
Now.
His radial velocity, however, would be about pi/2 radians (or the 90 degrees fling we see in the animation) in the same 0.267 seconds it took him to fly his entire height, so it would be about
pi/2*0.7 to get his approximate radial distance, which is about 1.099m.
*he flies this in 0.267* of a second, meaning his linear velocity by conversion would be 4.118m/s, which we also have to cram into that thing.

Adding the significantly less notable 4.118 m/s into the linear velocity gives that Sakamoto hit bro with a ball going at
*165, 951.4619 m/s*

By the fact Sakamoto had to hit the ball with a paddle to do this...
Assuming the ball has no starting velocity as whatever 100 m/s speed it could conjure wouldn't do very much at this scale,
The Ping Pong paddle weighs about 0.1kg, which is still a lot more than the 0.0027kg of the ball
By the same linear momentum equation used earlier:
(0.0027)(165951.4619) = (Sakamoto's arm velocity)(0.1)
Or about *ten times* what he hit the ball with, for a total of

Bro can swing his arm at
1 Million
659 Thousand
514.619 m/s

or about the *speed of a lightning bolt*

Assuming we use this plus the weight of the paddle to get its kinetic energy,
1/2 mv^2 is the formula for kinetic energy
plugging the values

Bro hit with 1410384.68 Kilojoules of energy.



*What in the actual fu-*

[jewelabyss]

This is the charm of Sakamoto Days. The fights have one of the best choreographies in animanga and the use of everything at hand as a weapon is always cool😆🔥

[thirtyfour]

i'm not sure if anyone else caught it, but sakamoto blinding one someone's eye (and slapping a '50% OFF MARKED PRICE' sticker on their other working eye, 1:33) was peak

[Dominicthedonkey]

that eye shot with the led felt brutal

[AmberHeardofme]

This is what one of the things I love of this Anime

[blazedoesblank]

The dude that said "Cast-iron Technique" then gets hit with a pan immediately will never not be funny

[Leo-Pekka]

Sakamoto Days is easily the best anime in the start of 2025 and it's impossible to kill Sakamoto!

[TheCandyManTeam]

People will say "Imagine if he used a real weapon" but the point is that he's so good, a real weapon wouldn't actually improve his lethality.

[biobiobio]

Badguy: behold my iron technique.
Sakamoto: slams whole fridge on badguy.

So...

He's like John Wick if he learned how to weaponize not just a pencil...

N E A T

[cyechan]

I'm not sure why everyone saying the animation is terrible
Looks fine to be a well directed

[johnmieleballes]

sakamoto days's animations are pure cinema

[DarkTribe]

Ok you have my attention. I need to start watching this.😅

[eriveragt]

the trailer on Netflix didn't look to good but now I need to watch this.
