The Unbreakable Gosaku is one of the most rewarding Mythic Tales in Ghost of Tsushima. Unlike some Mythic Tales that focus primarily on combat, this quest takes Jin Sakai across Toyotama in search of six stolen keys. Recovering all six keys allows Jin to unlock Gosaku’s Tomb and claim the powerful Gosaku’s Armour.
In this guide, we’ll explain how to start The Unbreakable Gosaku, where to find all six keys, how to reach Gosaku’s Tomb, and what rewards you receive for completing the Mythic Tale.
The Unbreakable Gosaku – Quick Details
- Region: Toyotama
- Act: Act 2
- Quest Type: Mythic Tale
- Main Reward: Gosaku’s Armour
- Mythic Tale Reward: Major Legend Increase
- Recommended: Complete the tale after unlocking access to Toyotama
How to Start The Unbreakable Gosaku
To begin The Unbreakable Gosaku, travel to Akashima Village in the Toyotama region.
Look for Yamato, the musician who tells Jin the legend of Gosaku, a farmer who became famous for defending his village from bandits.
Speak with Yamato to begin the Mythic Tale.
Once the story begins, Jin learns that Gosaku’s armour is protected behind a locked tomb. Six keys are required to open it, and the keys are held by Mongol-occupied settlements across Toyotama.
Your objective is therefore straightforward:
Liberate the six settlements and collect their keys.
Where to Find the Six Gosaku Keys
You need to collect six keys before you can access Gosaku’s Tomb.
The keys are obtained by freeing the following locations:
- Koshimizu Farmstead
- Iijima Farmstead
- Kuta Farmstead
- Yagata Farmstead
- Ohama Fishing Village
- Kikuchi Fishing Village
These locations are occupied by enemies, so each one must be liberated.
1. Koshimizu Farmstead
Travel to Koshimizu Farmstead and liberate the settlement from the Mongols.
After completing the liberation objectives, you will receive one of Gosaku’s keys.
2. Iijima Farmstead
Next, head to Iijima Farmstead.
Defeat the Mongol forces occupying the farmstead and complete its liberation objectives. Once the settlement is safe, you will receive another key.
3. Kuta Farmstead
The third key can be obtained at Kuta Farmstead.
Clear the Mongol occupation and rescue the villagers as required. Completing the objectives rewards you with another key.
4. Yagata Farmstead
Make your way to Yagata Farmstead.
As with the other locations, eliminate the Mongol presence and finish the settlement’s objectives to obtain the fourth key.
5. Ohama Fishing Village
The fifth key is found at Ohama Fishing Village.
Liberate the village and complete its objectives. Once the area is cleared, the next key will be added to your collection.
6. Kikuchi Fishing Village
Finally, travel to Kikuchi Fishing Village.
Free the settlement from the Mongols to obtain the sixth and final key.
Once you have all six keys, the location of Gosaku’s Tomb will become available.
How to Reach Gosaku’s Tomb
After collecting all six keys, travel to the location marked for Gosaku’s Tomb.
The tomb is located on a hill and is initially inaccessible.
When you arrive, look for the large stone gate. Jin can use the six keys to unlock the entrance.
Once the gate opens, climb the path toward the top of the hill.
Be prepared for enemies guarding the area. Deal with them before continuing toward the tomb.
At the top, interact with the tomb to complete the final part of the Mythic Tale.
Gosaku’s Armour
Completing The Unbreakable Gosaku rewards Jin with Gosaku’s Armour, one of the strongest armour sets for players who enjoy direct combat.
The armour focuses on stagger damage and health, making it particularly useful when fighting groups of enemies.
Its bonuses improve Jin’s ability to break enemy guards, and defeating staggered enemies can restore health.
This makes Gosaku’s Armour an excellent choice for aggressive sword combat.
Why Gosaku’s Armour Is So Good
Gosaku’s Armour works especially well against enemies with strong guards.
The additional stagger damage means Jin can break through enemy defenses more quickly, creating opportunities for powerful attacks.
The health-related benefits also make the armour forgiving during longer fights.
If you prefer to fight enemies head-on rather than rely heavily on stealth, Gosaku’s Armour is one of the best sets to obtain in Act 2.
Best Charms for Gosaku’s Armour
For an aggressive Gosaku build, focus on charms that improve melee damage, stagger damage, and survivability.
Good choices include:
- Charm of Inari’s Might – increases health and melee damage.
- Charm of Mizu-no-Kami – improves the timing window for Perfect Parry, Perfect Dodge, and related defensive techniques.
- Charm of Resistance – reduces incoming damage.
- Charm of Ferocity – increases melee damage.
The exact combination depends on your playstyle, but the general idea is to maximize Jin’s ability to stagger enemies and capitalize on openings.
Tips for Completing The Unbreakable Gosaku
Liberate the settlements as you explore Toyotama
You don’t necessarily need to treat the six locations as isolated objectives. If you’re exploring Toyotama during Act 2, liberating these settlements as you encounter them can save considerable travel time.
Use the Guiding Wind
Once the quest is active, use the Guiding Wind to navigate toward objectives and marked locations.
This is particularly useful when moving between the six settlements.
Use Stance Advantages
Different enemy types are vulnerable to different combat stances.
Use the appropriate stance rather than relying exclusively on Stone Stance. Switching stances makes clearing the occupied settlements considerably easier.
Take advantage of Ghost weapons
If you’re surrounded by several enemies, tools such as Kunai and Smoke Bombs can quickly turn the fight in your favor.
Don’t hesitate to use them during the settlement liberation sections.
Collect the armour immediately
Gosaku’s Armour is worth obtaining as soon as you can.
Its stagger-focused bonuses make it especially useful for the remainder of Act 2 and against heavily protected enemies.
Is Gosaku’s Armour Worth Getting?
Yes.
Gosaku’s Armour is an excellent choice for players who enjoy aggressive melee combat.
Its emphasis on staggering enemies and maintaining Jin’s health makes it particularly effective during large encounters where Jin is fighting multiple opponents.
It is less useful for players who primarily rely on stealth, archery, or assassination-focused builds, but for sword-focused combat, it is one of the standout armour sets in Ghost of Tsushima.
