If you're exploring Japan in Forza Horizon 6, you might want to capture the Koinobori fish flags for your Discover Japan collection. These decorative flags are only visible in certain towns during Spring, but there are ways to find them any time of the year.

1. Free Roam Locations (Spring Only)
During Spring, Koinobori fish flags are hung over streets in select towns. They often replace Tanabata Streamers when the season changes, so timing matters.
Here are the key locations:
Mei's House (Ohtani Region): Fast travel to Mei's House and look up—flags stretch across the sky above the courtyard.

- Tokyo Tower (Tokyo City): Located directly near the iconic landmark, perfect for snapping a scenic photo.
- Narai-juku (Shimanoyama): Traditional streets showcase the flags strung overhead, giving a classic Japanese vibe.
- Ito Region Coastal Town: Look along the northern bay coast for a beautiful seaside display of flags.

Tip: Use the in-game compass and mini-map markers to line up the perfect photo. The flags are always strung across roads or plazas, so keep an eye out above your car.
If you want to speed up your collection progress, you can also check out U4N for buying cheap FH6 credits—they're a safe and fast way to upgrade cars, buy items, and unlock special content quickly.
2. The Prologue Race Method
If it's not Spring in your game world, you can still find the flags during the Prologue race:
- Open the Map: Locate the Prologue race icon in the Takashiro region, featuring Mt. Fuji and the 2025 Toyota GR GT Prototype.
- Start the Race: Begin driving down the first hill.
- Spot the Flags: Koinobori fish flags will be visible hanging over the streets. Switch to Photo Mode to capture them as part of your Discover Japan journal.
This method guarantees access regardless of seasonal changes, making it reliable for trophy hunters.
3. The EventLab Method (Any Season)
If you missed Spring or the Prologue race, the EventLab lets you spawn the Koinobori flags anytime:

- Pause and go to the Creative Hub tab.
- Select EventLab, then Play Challenges.
- Press the Search button and enter a community Horizon EventLab Share Code for the “Koinobori” photo challenge: 142197341
- Start the event, drive a few meters, and switch to Photo Mode to capture the flags instantly.
This method is flexible and perfect for collecting the photograph without waiting for a seasonal reset.
