Can't find an email for them to ask. In general, will the coffee shops be open?

Cheers

Yes, all coffee shops will be open throughout easter, unless they have taken leave of their senses. It will be one of the busiest trading days of the year. Magic jesus has no influence over such things, I'm happy to report.

Thanks Withnail, this just made me spit my morning coffee across the breakfast table.
My Japanese hosts are wondering WTF this gaijin is on.
That'll have chuckling all day.
