So I was screenshotting the SE shores of Kyushu, and nearby small islands. Lemme tell you I found some scenic ones. Inspiring romanticism. The most notable difference between the state of medieval fishing village and modern one are these concrete embankments and the asphalt road snaking behind. Ofc they had roads similarly at the shore, following the feet of the hills.

Here's an site listing types of ships/boats Japans used "back in the day" before they modernized.

Two examples of fishing boats. The first one is a trawler.
