From what I see[1], that is an umbrella term that encompasses a few passes, including the Wide Pass. Maybe some do include attractions; I didn't know that!

I also looked up Tohoku JR passes for an upcoming trip and it wasn't affordable at all. I'm better served using single tickets even when riding the Shinkansen.
