Strollers in Shinkansen

We will be traveling to Japan in April and noticed there are some new rules for oversized baggage on the Shinkansen. I see that we now need to book specific seats (the last row) to store oversized baggage. However, strollers are exempt from this requirement. Is there still a location where we can store the strollers on the Shinkansen? I recall that towards the end of each train car there would be a storage area in the past (not behind the seat), but I wasn't sure if this is still the case. Please advise.
