purification hall of a Shinto shrine
A building within a Shinto shrine precinct where purification rituals (harae) are performed. The reading はらえどの is most common; はらいどの and はらいでん are alternative readings.
Before worship, I received a purification ritual at the purification hall.
Compound of 祓 (harae, 'purification') and 殿 (den/dono, 'hall, building'). The reading はらえどの is the most common; はらいどの and はらいでん are alternative readings reflecting different rendaku and on'yomi variations.
