Like A Dragon Hazardous Materials Exam Guide
The Hazardous Materials Exam appears in multiple games across the Yakuza franchise, most notably Yakuza 5 and Yakuza: Like a Dragon. It is a mini-game where you manage hazardous materials while completing jobs. The core loop is simple on paper: you get assigned a delivery or cleanup task, you have a limited amount of time and resources, and you need to transport or handle dangerous goods without triggering a spill or explosion. Here is how it actually works. You control a character who picks up hazardous material canisters from a starting point and delivers them to designated zones on the map. The canisters are heavy and slow you down. If you get hit by enemies, take damage, or collide with obstacles while carrying them, the canister can crack. A cracked canister triggers a timer, and if it expires, you get a game over for that attempt. The same happens if you drop a canister by walking off a ledge or taking fatal damage.

The first thing you need to understand is that map knowledge beats everything else. I spent about twenty minutes on my first run of the Yakuza 5 exam just getting flattened by random pedestrians while dragging a single drum. The map in those urban districts is tight, with narrow alleys and a lot of foot traffic. Once I mapped out the direct routes between pickup points and drop zones, the exam took me three or four minutes on average. There are a few things the game does not tell you upfront. One: you can carry multiple canisters at once if you have the strength upgrade or if the mission variant allows it. Two: you do not need to return to the exact starting point after each delivery. You can pick up a new canister from wherever you are as long as you are in a marked zone. This saves you a lot of unnecessary backtracking. The difficulty spikes when you introduce time limits and higher-tier materials. In Yakuza: Like a Dragon, the exam shows up during the Bito Enterprises arc and it is significantly more complex than the earlier entries. You are dealing with different classes of hazardous goods, each with their own handling properties. Radioactive materials move slower and cause more damage to your character over time if you hold them too long. Flammable materials have a shorter crack timer but deal explosion damage if they rupture near other canisters.
I ran into a specific edge case during a run with the radioactive canister where the intended route was blocked by a construction site. The game does not provide a map marker for alternative paths. I ended up having to go through a building on the second floor, which cut roughly two minutes off the total time but required me to navigate some tight indoor corridors. If you are stuck, try looking for interior shortcuts through any connected buildings near your route. The game generally lets you pass through these areas even if they are not part of the main path. Another counter-intuitive thing: running is not always better. Your character sprints faster, but sprinting while carrying a canister increases the shake factor, which makes the canister crack sooner. Walking at a normal pace while weaving through traffic is almost always faster overall because you avoid the damage from collisions and you do not risk cracking the container. The only time sprinting makes sense is when you have a clear path with no enemies or obstacles between you and the drop zone. There is no downloadable file for the exam itself since it is built into the games, but if you are looking for practice, the easiest approach is to boot up the relevant title and enter the exam mode directly. Yakuza 5 has it accessible from the substory menu after you reach a certain point in the Kasuga Ichimon storyline. Yakuza: Like a Dragon locks it behind the Bito questline progression. Neither version requires a separate download, so you should not run into any piracy concerns if you own the game.

The exam becomes genuinely tricky on the hardest difficulty setting, which is what most players aim for if they want the bonus rewards. On that tier, enemy aggression increases, the crack timers shorten by roughly thirty percent, and the maps include dynamic obstacles like moving vehicles that can block your path mid-delivery. I found that practicing on the medium difficulty for about ten to fifteen minutes total helped me internalize the safer routes before attempting hard mode. Going straight to hard without that warm-up usually results in three or four failed attempts in a row. If you keep failing the same mission repeatedly, check whether you are picking up the canister correctly. You need to press and hold the interact button for about half a second while standing in the correct zone. Tapping it quickly will not register, and you will just walk around looking confused like I did for the first five minutes. The rewards for completing the exam on harder difficulties include stat boosts that carry over into the main campaign. In Yakuza 5, finishing the exam unlocks increased health and strength modifiers. In Like a Dragon, the bonuses are slightly different but still meaningful for late-game combat. The main downside is that the exam can feel repetitive if you have done it multiple times, and there is no skip button, so you have to replay each segment from the beginning after a failure.
One last thing nobody mentions: the exam has a hidden checkpoint system. If you complete a delivery successfully, the game remembers that delivery even if you fail on a later attempt. This means you only need to rerun the sections you mess up, not the entire exam from scratch. I wasted probably thirty minutes on my first attempt re-running deliveries I had already completed because I did not know this existed.
