First of all, welcome to Japan!!!

thank you for the new information. Please do keep us posted on the prescription medication or any over the counter ones you try (if you do). It will help others with IBS visiting Japan.

Hey,

Never taken either, but I feel the train may be a slight bit easier (provided you get a seat).  According to the website, it has no step at the platform whereas a shuttle bus would have at least the step into the bas itself.

Keep us posted!

Hello again,

If you have any other issues, JR East has an English information line: 050-2016-1603 （10:00 ～ 18:00）
