Shinobi is a Sega of Japan IP, just like Streets of Rage 4 before it (another game Lizardcube worked on) they have to develop those titles respecting and following the inspiration and supervision of the Japanese creators because they are working as contractors. The developers are Western, but spiritually it is an Eastern game.
Mercury Steam and Retro Studio are also western developers but their work on the Metroid games did not deviate from Nintendo of Japan's supervision, standards or sensibilities, henceforth even if the work is geographically taking place in a Western studio, it is Easter inspired by the nature of the IP and its conception.
Meanwhile Assassin's Creed: Shadows is being developed by a French studio but that is an example of a game that pretends to have Eastern inspiration but it has Western minded "sensibilities" at its core and it shows.
