I find the idea very natural too, and there is precedent for this in Western tradition as well. In the times of ancient Rome, people would eat a meal with at their gravesite of a dead relative. This meal was called "refrigerium". https://en.wikipedia.org/wiki/Refrigerium

Interestingly enough, some necropoleis in those times were literal cities of the dead, made of structures with rooms where the dead were interred, and people could do the regrigerium in those "houses". https://en.wikipedia.org/wiki/Necropolis mentions this style of necropolis for the Etruscans, but it is my understanding Rome had these too at some point.
