The web page was initially designed to help people during disasters in Japan. Volunteers have translated it into Ukrainian and Polish.
Many Ukrainian children and their caregivers are struggling with nutrition and hygiene amid dire conditions. Sakamoto Masahiko, a pediatrician involved in the project, felt compelled to act.
"What's happening there isn't someone else's problem," he says. "After watching the unbelievable scenes, my biggest motivation was to ask myself, 'is there anything I can do?'"
Sakamoto once studied in Poland, which neighbors Ukraine and is hosting the largest number of refugees. He now works at a hospital in Nagano Prefecture, central Japan.
He says pediatricians should represent children's voices – even from thousands of kilometers away. "Please don't forget about them. I want many people to understand why it's important to help."
The web page, entitled "To Caregivers, Parents and Children in Ukraine," offers all sorts of advice.
One section shows how to keep children clean using just a towel wrung with hot water, and another dry one for wiping up. If there are none available, tissues can be used instead.
The site also addresses mental health. It explains that children often demonstrate unusual behavior during troubling times. Some may try to come to terms with their situation through war-themed games.
Another section is for women who struggle with breastfeeding due to stress. There are five tips, such as talking with others, and maintaining skin contact between mother and baby.
