Kai has a picture book explaining the sounds that things make in Japanese.

• A car goes boo-boo-boo-boo.
• The dog barks wan-wan-wan-wan.
• Water from a tap runs jaa-jaa-jaa.
• Papers rips like bili-bili-bili-bili-bili-bili.
• The vacuum cleaner goes buiin-buiin-buiin.
• A rooster cries kokekokkoooo.
• A railroad crossing (weird choice when one is limited to eleven pages) goes kan-kan-kan-kan.
• Babies from time to time go aan-aaan-aaaan-aaaaan.
• Airplanes make boon-boon-boon-boon.
• The cat meows nyan-nyan-nyan-nyan.
• A trumpet sounds puppuuu-puppuuu-puppuuu.
