We also saw some students at the train station (as can be easily seen from their serafuku :btr_kita_wave: ), so I'm guessing they're having their school trip arc.
I was staring out the window until we reached the first stop. Since it was a cloudy day, I could see the clouds move by SO quickly, due to the speed of the shinkansen. It was so surreal.
Besides that, it was mostly farmland and mountains.
We also got ekiben from the station. Mine had two tiers, one with two different types of rice and the other containing a variety of side dishes, like chicken, rolled omelette and mushrooms.
