The Tatami Galaxy - S01

On a hot summer day in Kyoto, a young man heads toward his apartment, dreaming of switching on the air conditioner and cooling off. But before he can make that dream real, disaster strikes, naturally, in the form of Ozu, who spills soda all over the remote. With the air conditioner completely unusable, the man and his friends are left to sweat through the terrible August heat. Just when all hope seems lost, the group finds a genuine time machine in their storage room. Not knowing the dire consequences, they decide to travel back to the past and grab the remote before Ozu even has a chance to destroy it. What awaits them on the other side is a staggering adventure none of them are prepared for.
