In my specific case, I was looking into travels between Beppu (Japan) and Osaka. There is a direct ferry line, but other routes exist of course (also trains).

I wonder how a ferry and a plane would compare

In theory I guess, but in practice we have diesel engine ships and all sorts of dynamics with pollution (e.g., using more dirty diesel that's forbidden but not in international waters etc).

    You mean bunker oil not diesel. First, it is what is left over from fracking so in itself isn’t polluting much extra in production. Then, as a ship is buoyant, it burns much less fuel per ton-km so it pollutes exponentially less than any other form of motorised transport. Planes are at the other end of the scale.
