I first played this game probably 9 years ago and when I saw this scene I instantly wanted to get a shamisen! Now 9 years later I just bought one and I love it! It is one with a thinner neck and skin but it still sounds amazing and has the sawari tone. Anyways I just to share this little piece of music because I find the phrasing to be brilliant and will hopefully inspire someone. Also wanted to ask, is the one in this video a Tsugaru Shamisen or another type? Cheers!
