筑波山と富士山の祖神争い

（『常陸国風土記』由来）

筑波山は貧しいながらも温かく歓待しました

The Dispute Between the Ancestral Deities of Mount Tsukuba and Mount Fuji

(Based on the *Hitachi no Kuni Fudoki*)

When the ancestral deity visited Mount Fuji and Mount Tsukuba:

Mount Fuji refused to provide lodging, claiming, ""Tonight is the night of the *Niiname-sai* (Harvest Festival), and I am observing ritual abstinence.""

Mount Tsukuba, though poor, offered a warm and hospitable welcome.
