Good news for Nagasaki: they’re finally being connected to the Shinkansen service. If you’d like to visit Nagasaki from Kumamoto, I’d recommend the ferry, which departs from Kumamoto Shinko and arrives in Shimabara - which in itself is a lovely town to visit (it’s famous for its streetside canals studded with koi) and then local transportation from there. It’s probably cheaper and faster. - William
