Tasokare Hotel

Both are representations of a sort of limbo about a place (Tasokare Hotel and Old Home) that hosts souls that are either dead or in the purgatory and the mystery that surrounds the inhabitants. The vibes are different but you might like the other series if you want a similar plot but with a different focus. 

Their genres and premise are very different but they seem very similar with them being very Japanese in appearance and also to do with a main focus establishment providing hospitality to its patrons, tho not set in your usual modern day Japan with more fantasy setting. Although their hotel purposes are different, one in providing hospitality to supernatural beings and the other providing abode for those in limbo of life and death trying to remember how they've come to be, both shows do have their light hearted funny moments mixed with some serious drama between as each episodic tale takes you on a storytelling of a particular guest, as well as figuring out stuff between the main casts too. If you like cute girls doing cute things in Konohana and it being more relaxed too, Tasokare may not be for you as it doesn't really have that aside from Neko fangirling at Ruri. If you like the mystery detective-like solving issues in Tasokare, Konohana doesn't really have this either. read more
