The Tatami Time Machine Blues (original) Tomihiko Morimi

In the boiling heat of summer, a broken remote control for an air conditioner threatens life as we know it in this reality-bending, time-slipping sequel to The Tatami Galaxy. During a scorching August in Kyoto, our protagonist and his worst friend, Ozu, are locked in a glaring contest in a four-and-a-half-tatami-mat room. Ozu has spilled Coke on the air conditioner’s remote control—the only AC in Shimogamo Yusuisuiso, their famously shabby sweatbox of an apartment building.
