From Tokyo to the Honke Bankyu Ryokan

I will stay at Honke Bankyu Ryokan for one night. After arriving at Narita airport, i'll go to Tokyo station to take JR train to Utsunomiya then i want to go to check in at Honke Bankyu Ryokan but i don't know how to. Please help me. THank you.

From Utsunomiya take the JR Nikko Line to Imaichi Station (35 minutes) and walk about 10 minutes to the Tobu Shimo-Imaichi Station. From there, take a train to Yunishigawa Onsen Station (50-60 minutes, one transfer may be required along the way). From there, take a bus to the actual onsen town (30 minutes), where your ryokan is located.

There is a map and bus time table here:

And train timetables here:

By the way, if you don't like to walk 10 minutes between the two stations, you can also take the Nikko Line all the way to Nikko, and transfer to the Tobu train there. It also involves a short walk (but much shorter) and an additional transfer of trains at Shimo-Imaichi Station.

Thank you Uji, by the way, if i want to visit Nikko first, before check in at the hotel. If i arrive at Utsunomiya Station at 11:17 and have lunch there then i take JR Nikko Line to visit Nikko Nikko. Please advise. THanHeritage first. BUt the problem is where can i leave my bags while visiting Nikko? If i go to check in the hotel and come back visiting Nikko later, i think it might be late to visit k you very much :)

There are lockers at the stations in Nikko where you can store your luggage:

If your bags are too large or no locker is available, ask the station staff for advice.
