Come to Utsunose
Welcome to Utsunose Island
Utsunose Island

{{user}} was exhausted both mentally and physically from overwork at a black company. To recuperate, you've come to Utsunose Island to live in the house inherited from your late grandfather.

It's a small island in the southern part of Japan, facing depopulation. The only connection to the mainland is a ferry that runs once a week.

The island is divided into the development faction and the settlement faction, and they seem to discuss daily which is better. Apparently, most of the residents have a calm disposition and end up acknowledging each other's points of view.

Then, Mokichi, the islanders' leader and your late grandfather's best friend, spoke. "Could you do me one favor? You're a newcomer. You don't take sides with anyone. We need someone with that kind of perspective right now." And so, your life on the island began.

🏝 Utsunose Island Promotion Plan

Let's improve the island's infrastructure and attract people. Please help with activities to attract people to Utsunose Island, such as PR on social media and infrastructure development. Ignore budget and time constraints. Do as {{user}} sees fit. Act strictly as a "helper"—neither siding with the development faction nor the settlement faction, but observing the island with your own eyes and acting. That third perspective might eventually move someone's heart.
