Har Dez's video: Ghost of Tsushima Kawachi Whaling Village

Kawachi Whaling Village is on the southwest side of Jogaku Temple, and one of the largest Outpost in this region. You can gain entrace to the large building here via the rooftops and inside you'll find the hostage along with many Mongols. This entrace is the best to go about it unseen, you can easily pass through all floors assassinating them before heading back up to free the captive. You'll need to head back up to the east to find the last two hostages, both of these have several Mongols guarding them along with dogs. You'll find buildings near both of them full with Mongols so work on taking them out first before focusing on the Mongols out in the open with the hostages. On top of the usual rewards you receive, you'll also obtain a Piece of Mongol Armor needed for the Fit for the Khan Tale.
