What gifts am I to give in Japan?

In homes with small tubs, each family member bathes one by one, in order of seniority, traditionally starting with the oldest male. However, many young Japanese women now refuse to bathe after their fathers. If there are guests in the home, they will be given priority. In homes with larger tubs, it is not uncommon for family members to bathe together. Typically one or both parents will bathe with babies and toddlers, and even as children grow older they may still bathe with one of their parents.
