When I first asked my friend from Kumamoto about getting to Shirakawa spring, she told me we had to use a taxi. Thankfully, there's a nearby train (I think the train isn't very well known). So after we checked out of Aso Farmland, we grabbed out bags and made our way to Akamizu station.
|Train to Shirakawa|
If, like us, you're traveling with baggage, you could ask the first shop on the road to Shirakawa spring if you can place your bags there. They took care of our bags for free (of course, do not leave your valuables in there).
|The station is beautiful!|
Now, for the more complicated part, Shirakawa to Kumamoto Castle. It's also possible to go from Aso Farm Village to Kumamoto castle using these directions, just follow them from Tateno Station.
From Minamiasoshirakawasuigen (南阿蘇白川水源), take the train to Tateno station. Change at Tateno to the JR line towards Kumamoto (熊本行き) and take train to Shinsuizenjieki (新水前寺駅). From Shinsuizenjiekimae (新水前寺駅), go to Shinsuizenjiekimae (新水前寺駅前) and take the train to Kumamotojyou Shiyakusho mae (熊本城・市役所前). You can walk to Kumamoto castle from there.
|This is not food.|
From the castle, go back to the same station and take the tram all the way to Kumamoto station. From there, you can take the Shinkansen back to Hakata.
And there you have it, a quick trip in Kumamoto by train :D
