Father’s Day was started in the U.S., but in Japan we celebrate it as well on the same day (please click here for more details). In Japan we say “お父さん、ありがとう (thank you, Dad)”, “父の日ありがとう (thank you on Father’s Day)” or “いつもありがとう (thank you always)” instead of “Happy Father’s Day (父の日おめでとう)”. Additionally, in Japan we only celebrate our own fathers and only our own fathers. Wives normally don’t celebrate husbands on Father’s Day, siblings don’t celebrate their brothers who have a child, and friends don’t celebrate men who have a child.
