Nakano neighbours noise complaints - seeking advice
I live in Nakano, in a quiet neighbourhood, about 15 minutes from the nearest train station and 20 from Nakano Broadway. I've noticed over the past two years, an increase in tourists in the area (i.e. there is a new block of flats which are all short term lets next to my apartment building, and at least two more Airbnb or short term let houses in the nearby vicinity with room for up to 8 people each).
Recently, though, it's gotten bad with noise at night. Over the past week especially, a group of guys have been yelling while coming home I guess from a night out (between 2am and 4am every night). I went out to confront them on the second night but it hasn't stopped them. I found the Airbnb they're staying in today as I saw them leaving with their luggage and I'm wondering how I can make a formal complaint. It's not just me, I spoke to some of the others in my block and they also were annoyed by the noise at night. But obviously they're only here for a week or two so it's the Airbnb or homeowner who is responsible. Does anyone have any advice on what to do? I would understand if I lived next to a busy street or near a party area, but it's quite clearly a quiet place and all residential homes.
Thanks in advance .
