This place is exactly situated between the Niigata university and the beach. You grandma lived in Niigata? Whow ! When has she been there? And may I ask what for? Niigata isn't very famous outside of Japan but it is a wonderful area with a lot of beautiful lansdscapes of the japanese countryside.
Really? Cool ! She must have known Niigata before the old canals that flowed throughout the city were filled in to make way for more roads... When it still was called "mizu no machi ", the city of water.
