Yoshimitsu is in fact very active in Matsunaga's life. Though most of the communication happens during dreams, sometimes Matsunaga will also hear a whisper carried by the wind.
As for when things go south, it's the times where Takemikazuchi becomes the most active, if you are observant enough you can feel the smell of ozone in the air around Matsunaga and a staticky feeling around him.
When he gets to come out and play it's a completely different matter, it's like two people joined at the hip who practiced fighting together a million times before. If Matsunaga goes into the offensive Takemikazuchi will lead a path open to him, if Matsunaga defends, he will use some tricks to attack at a distance. But at their core they are so compatible they work in tandem perfectly. In a weird sense Takemikazuchi is really happy that a kindred soul like Matsunaga exists in the modern era but also dissapointed that this youth has not manifested his true self yet.
