What’s a “koku,”
anyway?

'Tis a unit for
measuring rice.

Wait, they even
used rice to
describe the size of
domains and
villages? That’s kind
of wild.

Indeed. For people back
then, measuring things in
rice was familiar and easy
to grasp. D’you know those
1.8-liter sake bottles?

One koku equals 180
liters—that’s 100 of
those sake bottles!
