Trade, build a fleet, take the seas.
Earn through trade, gather companions, strengthen your fleet, and conquer the seas, fortress by fortress. Loved in Japan at 88 percent, but it has no English yet, so the West has not boarded. Just 1 English review exists.

01First, the one feeling
- You buy low in one port and the whole map tilts: you read where the next price gap is before anyone else.
- Then a fortress blocks the lane, so you decide whether to invest, recruit, or fight your way through.
- When a single trade run pays for the fleet that takes the sea, a chill runs down your spine.
02Who this is for (and who it is not)
For you
- You love the Uncharted Waters loop of trade, explore, and naval combat, and want it at a focused doujin scale
- You want to read price gaps and routes, then grow a fleet from a single good trade run
- You do not mind no English yet: the gem is the loop, and language is the only wall (just 1 English review exists)
Not for you
- You need a polished, English-first release right now (no English yet, and it is still in Early Access)
- You want fast action, not slow trade-route reading and fleet management

Give it your first passUncharted Waters II The origin
The origin of the maritime-trade taste: Koei's Uncharted Waters built three pillars, trade, exploration, and naval combat, into one loop of earning at sea and expanding. This gem distills that loop back down to a single solo-doujin scale.
