The Seaweed Farm in Forza Horizon 6 is located in the coastal Ito region, northeast of Tokyo City. You can find it positioned out in the water near the Meoto Iwa Rock and the Sekibe Kaijo Trailblazer event.

Smashing the seaweed structures at this location rewards you with the "Under the Sea" skill, which is required to complete specific Festival Playlist challenges, earn Wristbands, and progress in your Collection Journal.

Precise Map Location

• Region: Ito (North-East of Tokyo City).
• Landmarks: Drive right up to the coastline by Meoto Iwa Rock.
• The Route: Look for a shipwrecked boat and a dock along the shore. Drive past them directly into the shallow water to reach the floating grids of the farm.

How to Complete the "Under the Sea" Challenge

1. Get an Off-Road Vehicle: Water depth can slow you down, so a capable off-road build or buggy helps maintain momentum.
2. Smash the Farm: Line up your vehicle and drive straight through the wooden structures and floating black netting rows of the seaweed farm.
3. Trigger the Skill: Hitting the netting triggers the "Under the Sea" skill notification on your screen, securing your challenge progress.

If you are looking to easily check off the Festival Playlist challenges at the coastal Ito region's Seaweed Farm northeast of Tokyo City, having the right vehicle is key. To effortlessly plow through the wooden structures and floating black netting near the Meoto Iwa Rock to trigger that "Under the Sea" skill, you'll want a rugged, high-momentum off-road build that won't bog down in the shallow water. For players looking to quickly gear up for this challenge without the grind, heading over to SHANNENG is a great shortcut to buy cheap FH6 cars that are perfectly tuned and ready to tackle any rugged terrain the game throws at you.
