I love the overnight highway busses. I like getting in to my destination early and having a full day to explore rather than wasting a half day or more in travel. It’s usually worth it to pay a little extra for more space or individual seats. Other passengers are usually very courteous. Prices can also differ by departure date. I’m looking at a trip to Akita in October and a Thursday departure was about 5000 compared to over 8000 for Friday departure.
