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.

KK's investigation note locations

There are 20 KK investigation notes to find in Ghostwire: Tokyo. That's a total of 400 skill points you can spend on upgrading Akito's abilities, so seeking them all out is well worth your time! Six can be bought from special relic-hunting Nekomata vendors across the city in exchange for a hefty sum of Meika, while the other 14 are found via exploration (much like relics). Read on for every individual KK investigation note location.

Found in an off-map area only reached as part of the main story in Chapter 5. After the first boss fight, look inside the nearby hut to find this file on a counter between a tea set and a safe. (Note: This one is very easy to miss!)

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