Joetsu Shinkansen

We took the Joetsu Shinkansen from JR Tokyo Station to JR Omiya Station in Saitama Prefecture. This is an E2 series Shinkansen and we were in the Green Car. Plenty of seating space, luggage space, bathrooms, rooms for nursing, rooms for smoking, etc. One thing to note, it is polite to say "excuse me" ("suminasen") before leaning your seat back if the seat behind you is occupied.
