Sekiro Shadows Die Twice contains items called Treasure Carp Scales. This guide shows all Sekiro Treasure Carp Scale Locations. These scales are acquired by killing treasure carp and can be used at a vendor in Hirata Estate. He also sells a skill needed to acquire all skills for the Height of Technique trophy or achievement. In total the items he offers cost 15 treasure carp scales combined, but there are more than that.

Only Treasure Carp Scales #39-#42 of these collectibles are missable. Everything else isn't missable as you can still return to all areas later on. This guide lists them in chronological order. Most come from killing the treasure carp fish, but some are found as collectibles in the world. The treasure carp do not respawn once killed.

How to kill Treasure Carp
The carp are all found in water (thus easy to locate) and will swim away very quickly when they spot you but they respawn within a few seconds when you swim away to another area. To target them press the right stick (R3) so you can lock on to them even while they're underwater. There are basically two methods. Swim to them head-on and let them spot you, just spam sword attacks and hope to get lucky to land a hit. The alternative is to swim slowly behind them and follow them until they get closer to the surface. Later on you unlock the diving ability by killing the Corrupted Monk boss in Ashina Depths. This is an unmissable main boss. Once he is defeated you can dive down by pressing (R2) / (RT) which makes it easier to hunt the carp.

Hirata Estate

Treasure Carp Scale #1, #2, #3, #4: Dragonspring - Hirata Estate
The first 4 carp are swimming in the lake where you find the vendor. In Hirata Estate region, at the first idol called "Dragonspring" jump down the cliff and you'll find a big lake on the right side. The treasure carp swim away quickly when they spot you, but can be killed with sword attacks when timed correctly. See the above section on how to kill them.

Treasure Carp Scale #5: Dragonspring - Hirata Estate

Treasure Carp Scale #7: Bamboo Thicket Slope [Requires Diving]
In the same river where our last carp was, but this one is downriver. It's deep underwater and can only be reached with the diving ability.

Where we bought the last two scales from the merchant, walk down the river, it's at the very end of the river as a normal item pickup (not a fish this time).

Treasure Carp Scale #13: Water Mill [Requires Diving]
Jump in the river left of the Water Mill idol. Swim to the end of the river and dive down to find this fish. If you don't have the diving ability yet, you get it from the main boss "Corrupted Monk" just after the Water Mill idol, he's only a minute away.

Sunken Valley

Two of them are in this lake. Press R2 / RT to dive down and L2 / LT to swim up.

Ashina Castle (2nd Visit)

Treasure Carp Scale #17: Ashina Castle [Requires Diving]
After defeating the Corrupted Monk & Guardian Ape and getting the 2 ingredients from the caves they were guarding, you need to return to Ashina Castle. The idols will be locked, but you can get back there through the Abandoned Dungeon area. Now you can dive in the water below the bridge where the Ashina Castle idol was (diving ability unlocked by defeating Corrupted Monk). There's 1 single Treasure Carp in the water here.

Fountainhead Palace

Treasure Carp Scale #19-#21: Mibu Manor
After the Mibu Manor idol you come to a courtyard filled with flute-playing squid enemies. At the end of that courtyard in the top left corner is a little water hole. Dive through it and on the other side you find 3 carp scale as a normal item pickups. Also be sure to open the big chest here. This chest contains the quest item "Water of the Palace" which we need for our next carp scale.

Treasure Carp Scale #22-#26: Mibu Manor / Ashina Depths - Water Mill
After getting the "Water of the Palace" (see last 4 scales above), head back to Ashina Depths - Water Mill. On the way to where you fought the Corrupted Monk is a house with a mob of enemies gathered in front of it. You can crouch under the right side of the house and enter through a floorboard underneath the house. Inside there's a man who wants the "Water of the Palace". Give it to him, rest at an idol, then return to defeat him for 5 Treasure Carp Scales.

Treasure Carp Scale #27-#38: Great Sakura
After defeating the Okami Leader Shizu miniboss you can jump in the big lake. There are 7 Treasure Carp Fishes swimming in there. Dive down to kill them. Another 5 scales are found as underwater item pickups so make sure you pick up everything in the lake. That's a total of 12 scales right there in the same lake.

Treasure Carp Scale #39-42: Feeding Ground
From the Palace Grounds idol, enter the next building (very dark with squid enemies crawling around) and take a right turn. This leads behind the building. From there grapple up to the roof and from there to a tree branch on the left, a temple roof, and lastly to the area on the far left. This brings you to the Feeding Ground. There's one character here and a bell. Ring the bell to summon the Great Colored Carp and feed it 2 x Precious Bait to get 4 Scales from it! The precious bait is also found as item pickups in the same lake where the last 12 scales were, so you probably found this in the process already.

That's all the Treasure Carp Scales in Sekiro Shadows Die Twice. You can find another Scale Merchant in Fountainhead Palace to spend your remaining scales. After the Palace Grounds idol, exit the next building to the left, then turn right to see a waterfall. There's a tunnel in the mountain not far from the waterfall that you can grapple to, and this leads you to the second Scale merchant.
