I love Keiko Sena's picture books and used to read them often. "Iya da Iya da," "Ninjin," "Nenai Ko Dare da," and "Moja Moja" are especially worn. I look forward to purchases from those who understand that these are used items. A fun set of picture books for children. Featuring vibrant illustrations and unique characters. - Title: Gittan Bakkon - Title: A-n A-n - Title: Iya da Iya da - Title: Ninjin - Title: Nenai Ko Dare da - Title: Moja Moja Thank you for looking.
