In October 2026, First House Mizonokuchi 100⁺a and 100⁺b got together for the Tamagawa Fireworks Festival.
After a few years of rainy fireworks nights, this year the sky was completely clear, and residents watched the show together from the rooftop. Afterwards we split between the living room and the outdoor area for a BBQ, and celebrated a housemate's birthday too.
Around 60 residents from the two houses joined, and it was a day for making friends across both houses.
