I have heard about the true story of Hatchiko when I was young child
Although I am in no way born before WWII (I am a GenX) , I heard the story from my aunts and uncles and my dad and mom. I guess it was a story that spread around the world at that time.
To see it adapted in a movie of today, the impact was the same or perhaps even more. This is so moving. My tears kept falling. Please watch this movie and learn from it.
