Hello everyone, we're looking to purchase a house in Japan within the next two years. Currently, we are in negotiations with several traditional countryside houses in Japan. We are aware that Japanese regulations regarding house extensions or additions can be quite strict and may potentially cause issues within the neighborhood sometimes.
Additionally, we are curious to know if it's feasible to build a private outdoor pool on our land (complying with legal requirements) and whether it's possible to install a private jacuzzi or spa, either inside the house or within a dedicated relaxation area in the garage.
We've attempted to research this information online, but we haven't been able to find any definitive information indicating whether such activities are prohibited by Japanese law. If anyone has insights into the relevant legislation in Japan, we would greatly appreciate it. Thank you!
