21 December 1576, Mount Kasuga, Japan - Wheel in the sky
Type of Spiritual Experience
A description of the experience
As quoted in Wonders In The Sky - Unexplained Aerial Objects From Antiquity To Modern Times - and Their Impact on Human Culture, History, and Beliefs - Jacques Vallee and Chris Aubeck
A wheel-shaped object flew for an hour over the castle on Mount Kasuga. No historical source is given for this tantalizing case, which would deserve further study by researchers familiar with Japanese chronicles.
