Checking out the Daimyo Machi Catholic Cathedral's website, as you do, I came across a Japanese word I'm sure few Japanese know: 大斎 (daisai).

It Latin, daisai translates as jejunium, or "[major] fasting" in English. Another word for fasting in Japanese is "danjiki" (断食), but that word doesn't seem to be used in reference to Catholicism. (I could be wrong, though.)

A counterpart of dasai is shosai (小斎) or “small fasting”.

Daisai (大斎) refers to the eating of one regular meal a day and two smaller meals and should be performed on Ash Wednesday (yesterday), and every Friday and Saturday of Lent, the 40-plus day period that culminates with Easter Sunday.

Shosai (小斎) refers to not eating meat and abstaining from things or activities one enjoys. (Hey! Where's the fun in that?)

If you are elderly or infirm, you get a pass. Kids, too, don't need to participate. (Ah, if only my father had known that!)

Anyways, . . .

I never cared much for Lent as a child. Who did? In our family, there was no meat on Fridays—but we had really good fish and chips then, so no big woop—long fasting from Saturday to Sunday morning Mass, only rice on Wednesdays, and worst of all: NO TV for the entire Lenten season. Talk about hell on earth for a young kid!

In this Era of COVID-19, the Daimyo Cathedral has requested those feeling ill remain at home. Ye of little faith. Tsk, tsk.
