Six Blades of Kojiro Weapon Completion Guide for Collectors

The open-world landscape of Ghost of Tsushima offers numerous challenges, but few are as memorable or as intense as the legendary questline involving Kojiro. Completionists and collectors who wish to fully check off their weapon collection milestones must hunt down five formidable Straw Hat assassins scattered across the Toyotama region. This comprehensive guide details the precise requirements needed to secure every accolade and complete this Mythic Tale efficiently.
Initiating the Mythic Tale in Umugi Cove
Before you can begin tracking the swordsmen, you must reach Act 2 of the main campaign and gain entry to the hidden village of Umugi Cove. Seek out Yamato, the traveling musician, who is resting on the back deck of the local inn to hear the grim legend. Speaking with him triggers the quest parameters, effectively marking the broad locations of your upcoming duels across the map terrain.
For players attempting to document their journey or verify quest metrics, using tools like the GOOGLEFINANCE function can help track virtual completion times or personal progression spreadsheets. Preparing your character with full resolve slots and defensive charms before leaving the sanctuary of Umugi Cove is highly recommended. These consecutive one-on-one sword fights will test your fundamentals on varying battlefield layouts.
Defeating the Five Straw Hat Assassins
The initial phase of the collection journey requires players to win five distinct duels, each located near unique natural landmarks in Toyotama. You will face Yasumasa at the Duel in the Drowning Marsh, which forces you to navigate a restrictive, swampy environment. Meanwhile, Hirotsune waits at the Duel Among the Spider Lilies, situated in a visually striking field covered in vibrant red flowers.
The remaining three combatants require careful exploration of the coastal and mountainous borders of the map. You must locate Kiyochika along the rocky shores of the Musashi Coast, Tomotsugu below the cliffs of the Cloud Ridge Shrine, and Kanetomo near the eastern hills of Yamabushi Peak. Each master swordsman employs a slightly different combat rhythm, demanding precise parrying and patient counter-attacks to defeat.
The Final Showdown at Omi Monastery
Once all five initial Straw Hats have been bested in combat, return directly to Umugi Cove to speak with Yamato a final time. The musician will reveal that Kojiro himself is waiting to challenge your skills within a secluded cavern. Navigate to the far northwestern corner of Toyotama to reach the Omi Monastery grounds.
Follow the guiding wind past the large red tree near the waterfalls to locate the entrance to the Mirror of Sacred Light cave. Inside, Kojiro will engage you in the most aggressive and mechanically demanding duel of the entire questline. Defeating this legendary warrior completes the quest and adds the highly coveted Kensei Armor and matching Kensei Headband to your permanent inventory collection.
