Japanese public restroom cleanliness

My family and I visited Japan in June of last year. We spent several days inside Tokyo Disneyland resort. I want to say the hotel accommodations inside Disney were fabulous, even the Double tree hotel in Kyoto was top notched. My question deals with the public restrooms whether it be inside the disney resort or out in the city or at Haneda airport. The public restrooms in Japan look clean but they sure don’t smell clean. It seems like this was predominantly the case everywhere I went. For some reason, their public restrooms reek urine. I am not sure if this had to do with the way they clean their restrooms. You know the smell of urine if you smell one. Same kind of smell if the urinals are not being flushed every time someone uses it.
I wonder if it is just me and my sensitive nose, or some of you had the same experiences
