Most of the achievements in Yasuke Simulator are unmissable, meaning you will get them just by playing the game. This guide will cover the ones that ARE missable
Moto Bomb

Chapter 2 in 3 minutes
The main trick will be juking the enemies in the carriage. Start by moving against the left and when you see an opening, going right, and be sure to roll out of the way if you get stuck. It may help to thin out their numbers before attempting this maneuver.
Also remember to hold out your gun and pick up ammo as you will need it for the final boss
Try not go get too hung up on using the bike for the bike section. If the geometry is being fussy it is often times better to get off the bike and run to a new one (since there are plenty laying around.) The main thing will be completing the Bike section before 1 minute 30 seconds
It is also important to remember that you can use the gun to shoot the Daruma dolls out of the way so that they don’t stun you.
You will also need to reach the crab boss by 2 Minutes 20 seconds. The trick to kill the boss quickly is to get close to him and shoot his body rapidly. You can also shoot around the base of his eye stalks for critical hits, but it’s unreliable and shooting the body goes fairly quickly
Hatchi Roku

Double Iron
In chapter 4 you can find the double pistols by taking a path to the left and turning the corner

If you go into the door on the left, you should also find the shotgun for the shotgun achievement,
Chapter 6 quick tip
Takeda Deer and Isekai
- You must clear the initial traffic section by around 30 seconds
- First, you must kill the mobs quickly to meet your quota. Both the UMP and Shotgun are good for this
- You must cross the platforming section on your first try, watch the Timing on the swinging poles
[shot] - Use the gun to clear the Takeda Deer
[shot] - You must reach Kei man by around 2 minutes and use the time in his startup animation to break the Japanese objects behind him
[shot] - Get UNDER Kei man and use the UMP to deal damage quickly

Chapter 8 in 3 minutes
First off, the statues are NOT solid so you can run through them for shortcuts
If you go into first person and line up the V in the shotgun sight with the robes on the mobs, it will be guaranteed 1 shot kill.

You can quickly meet your objects quota with this basket on the staircase if you hit it from the right angle, but if you only get to 20 objects do not linger as the time restrictions for this chapter are very tight and there will be more Japanese objects to break on the roof

The key takeaways are you must reach the 3 Takeda generals before the 1 minute mark and you must defeat the 3 Takeda generals by the 2 minute mark so that you will have enough time to platform to the roof.

The trick I use to kill the Takeda generals quickly (and similar enemies) is to first use the shotgun to clear the smaller mobs, then take out the UMP and go into first person mode. Fire in short bursts and aim for the head. Each headshot with the UMP does 60 damage and because of it’s high rate of fire you can deal a lot of damage to the generals quickly. Be sure to fire in short bursts so that you can maintain accuracy

A major timesave you can do is to run across this narrow walkway, but it is extremely janky and will take several attempts

Chapter 9 in 3 minutes
Right at the start there is a shortcut where you can drop through the slats at the start of the level for a shortcut
[shot here]
For most of the chapter you will want to use the UMP, as the enemies here have lower health than the regular enemies. If you strafe and shoot you should get kills quickly. I always make sure to clear 9-10 of the regular enemies right at the start. Be sure to ignore the generals as you do not need them to hit quota
[shot here]
Remember to jump down staircases when you can to save time.

For the section where Daruma dolls drop, bait out the dolls then clear them with one of your guns

The key to beating this chapter Is to make it to Motonobu with at least 19 kills BEFORE 1 minute and 20 seconds
[shot here]
The reason for this is he has a 25 second unskippable cutscene that has to play out before you can start the fight. When the fight does start, he will spawn in 5 regular enemies, which including himself will let you barely hit quota.
[shot here]
From there You must beat Motonobu before 2 minutes 35 seconds as it takes at roughly 30 seconds to run to the helicopter. Use the 1st person UMP trick I taught you for Chapter 8 to kill the 3 Takeda generals to beat him quickly. A trick I used was to bait his attack animation, step back, and then get quick headshots with the UMP
[shot here]
Once he goes down you will have precious few seconds to reach the Helicopter
