At first time visiting Japan

I had no choice but to go to toilet at Narita Airport

I didn't know why a button was here but tried to push it

Water came out

Wash my ass hole automatically

At first time visiting Japan

Just to make sure, I went to toilet at Okinawa Naha Airport

I'm a super curious man so I pushed the button

Hot water came out

Wash my ass hole automatically

Ah, beautiful shower time
