Turned out this bow blueprint can be obtained from gacha inside this game. Yes, gacha but not wishing system.
In short, you will have to open 1 out of 3 box daily and rely on your luck to get Hamayumi Bow blueprint, 1 chance per day.

So what you need to do next is investigating beach in front of his shop to get some Mysterious Conch. You won’t automatically get the conch everytime you investigate the spot, sometimes you will get mora, crystalflies, even enemies.

Keep gathering until you got 3 Mysterious Conch.
It’s Gacha Time
Do any rituals you want before doing this, might wanna try checking your luck using Fortune Slip in Grand Narukami Shrine.
Talk to Takashi and give him 3 Mysterious Conches you’ve get from the beach and you will get a chance to open 1 chest behind him.
