I have been studying Japanese architecture and floor plans and I'm getting a grasp on what a lot of the rooms mean and how they name them, but in this floor plan, there are two small areas on the top floor (吹抜) that seems to translate to "atrium" or "open ceiling". They're inaccessible and small. Of course, I know what an atrium is in Western architecture, but those are usually, y'know, accessible and central.
If anyone can explain what this would typically look like or even show an example, please let me know. Thank you!
