Am not sure I’ve ever had a PASMO card. Usually we reload the same Suica cards we’ve been using for years. This last visit, my daughter got her very own, it has the kanji for child printed on it and entitles her to half price travel.
Our preference is probably due to a fondness for watermelon and penguins, there’s also the joy in saying “Suica” - it just sounds happier than “PASMO” (thanks to an old thread in this forum, I often look at the card and read “Sucia” and that makes me giggle. “Spasmo” makes me wince)
