A five-chapter adventure about a Japanese girl and her grandmother living with Alzheimer's. In this comedic-yet-bittersweet story, explore your hometown, befriend quirky neighbors young and old, and surf their Y2K-inspired homepages! So... what’s a "danchi"? It's a Japanese mass housing complex, with plenty of neighbors. Of course, it's not always cheerful: the danchi is home to societal challenges, from aging seniors, to dementia, loneliness, and more. By gingham games - that's sandy powde...
After living overseas, 12-year old Hoshino returns to Japan to live in her childhood danchi (a Japanese mass housing complex). Her grandmother, now living with dementia, motivates Hoshino to revive the danchi's now-cancelled summer festival.
Why was the festival tradition cancelled? Who wants to stop Hoshino from reviving it? And what caused her hometown to decline in the 7 years she was away?
Explore Hoshino's danchi, uncover forgotten truths, and reconnect with her neighbors in... Danchi Days!
The world of Danchi Days is full of people from all walks of life - from quirky seniors teaching you about the pleasures of chatting, to brooding high-schoolers who desire nothing more than to escape their hometown! In her quest to revive her hometown's summer festival, Hoshino will invite all sorts of people to the festival.
Hoshino's dad made "NeighborNet" - a place where neighbors share their websites! Search keywords to find pages to surf, and learn more about your world. But watch out! Some websites are... darker, malevolent, even. Not everyone views life so positively... and not everyone wants Hoshino to revive the summer festival.
Our heroine, Hoshino, also hopes to become a Sense Master! By focusing in on the mundane world around her, she can find wonder in unique "Sense Games", where she'll bump into trees to smell them, collect beads of condensation from iced tea, and even listen to the sounds of neighbors' toilets! You never know what you'll encounter in these everyday minigames, or what clearing them might lead to!
A lively 6th grader! Her dad's job took them both to the USA for 7 years, but recently, they've returned to her hometown of Another Danchi to live with her grandmother. She hopes reviving the summer festival will help her grandmother's dementia get better... but will it really go so smoothly?
Former kindergarten principal, and Hoshino's beloved grandma, who once led the organizing of the summer festival! She's been living with dementia for a few years, but in the past, Hoshino and Rio learned all sorts of things from her. What led her to the decision to end the summer festival?
Born and raised in Another Danchi, Rio and Hoshino were close childhood friends. But ever since Hoshino moved back to the danchi, Rio's been acting distant towards Hoshino and her grandma... in those 7 years that Hoshino was gone, what did Rio experience, and why did he change?
Your trusty festival assistant kappa, avid poet, and local danchi god! One day, at the top of the danchi's water tower, Hoshino summons him to assist with the festival preparations. However, he seems to remember little of his past beyond the rituals for reviving the summer festival. What is his relation to the danchi and its festival? Can Hoshino help him get his memories back?
There's all sorts of other neighbors to meet!
