Love the concept for this (not enough Meiji-era games out there!), hope I can get a table for a one-shot once the pandemic dies down.
A small thing I noticed: in the description of Amazake-baba, you describe amazake as "Japanese sweets" -- amazake is a traditional low-alcohol Japanese drink, which is a bit more specific than the description suggests. Probably not worth a patch by itself but maybe worth noting if you're aiming for accuracy? Great work overall!
