Where to find all KK Investigation Notes in Ghostwire: Tokyo

Gather KK's investigation note collectables for a skill point boost, plus some extra lore!

Where can I find KK's investigation notes in Ghostwire: Tokyo? KK's investigation notes are a series of documents you can collect while exploring the world of Ghostwire: Tokyo. This spooky open world explore-a-thon was one of our favourite games of 2022 and has just hit Game Pass, so now's a great time to start hunting ghosts and collectables both!

Not only do KK's case notes make for interesting reading, there's a practical benefit to picking them up, too. Snagging one of these innocuous-looking documents nets Akito an instant 20 skill points — nothing to be sniffed at when upgrades on the skill tree get increasingly costly as you go on, and even levelling up only nets you 10 points at a time. To be absolutely clear, these aren't side missions: you don't need to do anything other than pick up the document to get the points, which makes them well worth seeking out by following our directions below.

Why has KK left his notebooks scattered all over Tokyo? Perhaps some mysteries are fated to remain unsolved.
