Yokohama Underground Enemies, Encounters, Items and Walkthrough
Dive into the Yokohama Underground in Like a Dragon: Infinite Wealth! Learn about enemies, valuable items, and get a walkthrough for this challenging dungeon.
Alright, let's talk about the Yokohama Underground in Like a Dragon: Infinite Wealth. This place pops up around Chapter 10, and while you can technically rush through it, there's a ton of good stuff to find if you stick around. Think of it like a mini-dungeon crawl where you can snag better gear, tons of cash, and valuable crafting materials. It's pretty similar to the Hawaiian Haunt, but with its own unique twists.
The whole dungeon is basically 40 randomly generated floors, broken down into four sectors of ten floors each. Each sector has a midboss and an endboss, and beating them gives you a checkpoint. Don't feel like you have to clear every single room, though – just find the stairs and you can move on or even bail out entirely if you need to. The deeper you go, the tougher the enemies and the better the loot!
Yokohama Underground Layout and Encounters
Here's a quick rundown of what you can expect on the first few floors:
| Floor | Characteristics |
| 1st | Entry floor, checkpoint, low treasure |
| 2nd | Standard floor, low treasure |
| 3rd | Standard floor, moderate treasure |
| 4th | Standard floor, high treasure (one guaranteed chest at the floor exit) |
| 5th | Boss floor, healing minifridge, save point |
Now, unlike the Hawaiian Haunt, Yokohama Underground doesn't mess around with an easy intro sector. You'll be thrown into Sector 1 with Level 39 enemies right away, and it just ramps up from there, hitting Level 55 bosses by the end of Sector 4.
| Sector | Enemy Level |
| Sector 1 | 32~ |
| Sector 2 | 37~ |
| Sector 3 | 44~ |
| Sector 4 | 52~ |
You'll also notice some key differences:
- Materials: You'll be grabbing Geodes in Sectors 1 and 2, and then upgrading to Crystals in Sectors 3 and 4. These are super important for crafting better weapons.
| Sector | Materials |
| Sector 1 | Geodes |
| Sector 2 | Geodes |
| Sector 3 | Crystals |
| Sector 4 | Crystals |
- Enemies: Forget Metalworms! Here, you'll be dealing with Invested Vagabonds, which are awesome for racking up tons of EXP to level up your characters. You won't be leveling up your Jobs as fast here, though.
- Currency: Instead of Data Disks, you'll be collecting Geomijul’s Survey Data. You trade these with Utamaru for different rewards. The more you find, and the deeper you go, the more you'll get from enemies, shinies, and completing floors.
- Chests: Chests pop up more often on floors 3 and 4 (out of every five), but it's not super strict. You might even find two in one room sometimes! Keep an eye out, especially in Sectors 3 and 4, because these chests can contain some seriously powerful, class-exclusive seven-star armor.
Yokohama Underground Armor Rewards
Here’s a peek at some of the seven-star armor you might find:
| Sector 1 | Sector 2 | Sector 3 | Sector 4 |
| Combat Knife | Eternal Slaughter | Armor of a Unified Nation | Home Mistress Dress |
| Combat Sword | Funny Bag | Jonin Vest of the Iga-Ryu | No. 1 Jacket |
| Hyper Plasma Mop | Hefty Chinese Saber | Super Lady Bondage | Representin’ Homies Top |
| Meow Meow Whip | Revival Microphone | Three-Star Chef Coat | Shiny Dream Dress |
Yokohama Underground Rescue Rewards
Just like in the Hawaiian Haunt, you can find people to rescue in Yokohama Underground. There are twenty in total, five per sector. When you rescue five people, you can chat with Utamaru to get a reward. Rescuing someone usually involves finding a group of enemies surrounding a Geomijul agent. You'll have to pick a fight, beat the agent and their pals, and they'll give you some Geomijul’s Survey Data before heading off. It's a good way to get extra currency and help out the locals!
