Of all the requests NPCs will make in Sekiro: Shadows Die Twice, the Abandoned Dungeon’s surgeon
Where to find a tough man in Sekiro: Shadows Die Twice

There are two men who fit the description in the Surgeon’s Bloody Letter, and while we’ll detail both below, it’s important to understand the implications of luring them to the dungeon. Should you trick either of these NPCs to visit the Abandoned Dungeon, they will disappear from the game, presumably having died. You won’t be able to continue their questlines, but you will receive a reward and new items at the Memorial Mob merchant. With that in mind, here are the tough men you can choose.
Tough man 1: Jinzaemon Kumano

Location: Ashina Castle - Ashina Reservoir
The first NPC you can lure is Jinzaemon Kumano, a noble warrior who patrols the moat. He can be found near the entrance to the well in which you started the game, reached from the Ashina Reservoir idol. If you’ve already defeated the Lone Shadow Longswordsman, he’ll then move forward to within the Abandoned Dungeon. Jinzaemon is looking for a Shamisen player who’s melody he can here. He’ll pop up again several times throughout the game, and if you complete his story you’ll get a special Jinzo statue. Sending him to the dungeon instead will reward you with 3 Lumps of Fat Wax for use in upgrades. You’ll also be called cruel by the Memorial Mob merchant near the dungeon entrance.
Tough man 2: Kotaro

Location: Senpou Temple, Mt. Kongo
Kotaro is a large and sad man you’ll find near the entrance of Senpou Temple. After speaking with the Buddha statue, turn right and jump down the path to find him sitting against a tree. He’ll say he needs to find the “pure white flower” to remember. You’ll find two flowers in the area as you explore Senpou, a red and white flower and a pure white flower. If you want to progress Kotaro’s quest, you’ll need to give him the white flower and obtain the Divine Abduction shinobi prosthetic tool, but to lure him to the dungeon (or the Ashina merchant) give him the red and white flower. Once again you’ll receive 3 Lumps of Fat Wax but lose out on his quest.
Much later in the
Now that you know where to find a tough man in Sekiro: Shadows Die Twice, you might want to complete some of the other NPC quests available. Did you manage to find the rats for the Ashina Tengu? We can also point you to all the shinobi prosthetic tool locations.
