Beppu is a city in Oita prefecture on the island of Kyushu, Japan. Beppu was once known as the Las Vegas of Japan, a reference more to its extensive sex industry than gambling. The resort has been attempting to clean up its image. To non-Japanese tourists, the sex industry may not be as obvious.
The Sonic limited express train runs twice an hour from Fukuoka (Hakata) and Kokura, stopping at Beppu before terminating in Oita. If you are coming from Honshu on the San'yo Shinkansen line (such as those holding Japan Rail Passes), switch to the Sonic at Kokura station. From Kokura, you can reach Beppu in 75 minutes at a cost of ¥4290 each way.
An overnight train, the Fuji, runs from Tokyo Station to Beppu in 17 hours, departing Tokyo at 6 PM. If you want reach Beppu in a shorter amount of time, you can take the 10 PM Sunrise Izumo/Sunrise Seto to Himeji, take the San'yo Shinkansen to Kokura, then take the Sonic to Beppu.
