"They're so skilful," some of the children said. But others gasped in horror.
Whale is a rarity on most Japanese tables, but Wada residents regularly eat it at home and in school lunches.
"It's so good," said Taishi Makino, one of the pupils.
In Wada, souvenir shops, restaurants, supermarkets and whale speciality stores line the streets, selling whale meat products and dishing up everything from whale sushi to fried whale.
"Here in Wada we eat whales. Every family eats whale at least once during the summer whaling season," said Michiyo Masuda, the students' teacher. "If we are eating whales, we have the responsibility to see and learn how they're prepared."
At her school, 10-year-olds study the biology of whales, the history of whaling and how to cook the meat.
"For us, whale is food. Whaling is a good tradition, and I want to pass on the trade before I die," said Shoji, who gives talks in schools and whose firm processes and sells whale.
Japan's international whaling programme suffered a blow when in March the International Court of Justice ordered a halt to its "scientific whaling" programme in the Antarctic. Japan agreed to cancel whaling in the Southern Ocean for 2014-2015.
