A quote from Gary Konik's Meteor & Comet Page:
"A meteor shower was predicted and observed by Japanese observers during 1930, with an unexpected outburst of 60 or 70 per hour (this is not a corrected zenithal hourly rate, but the raw numbers) occurring on the nights of June 9 and 10. The possibility exists that another outburst could occur in 2006, although the chances for a strong shower actually improve in 2022"
