Technology development upgrades are available upon completing the mission ‘Locating the Camera’.
Igashichi is always located in the same building as the photographic studio.
In Yokohama, this is in the Honcho area, not far from Miyozaki pleasure district.
Assassination (Gliding)
This upgrade allows you to assassinate enemies while gliding above them.
This is automatically obtained at the start of ‘Locating the Camera’.
Unlocking this requires 2,000 coins and a Level 1 bond level.
Just to make things confusing, the requirement it states in the menu is ‘Gliding Training in Yokohama’.
Once you’ve completed the challenge and been awarded the key item, fast travel back to see Igashichi.
It allows you to drop earthenware balls from the air while gliding.
Unlocking this requires 4,000 coins, 30 Foreign books and just a level 1 bond with Igashichi.
That’s it for the glider upgrades.
