DLC for Japan Playthrough

[Uncle Rico]

I’ve just started eu4 after enjoying ck2. I’m almost done my first game as France and I want to start a game as Japan. I only have the base game and I’d like to pick up some DLC that will work the best to improve a playthrough as Japan. Any ideas?

Mandate of Heaven

Definitely Mandate of Heaven because it adds shogun mechanics
