old habits + old technology = predictable results
old habits + new technology = new, unpredictable results
If a country were to shoot nuclear missiles all over the place(as an example) as if they were just cannonballs, the results would be devastating. Similarly, with whaling, new technology ensures an extremely high kill rate compared to the older technology and techniques of the 8th century, when Japanese whaling was first recorded. During the 8th century, many boats would have to surround a whale to prevent it from moving out of range of their hand-thrown harpoons and then the crew would have to throw their harpoons, sometimes missing. However today, because of advanced technology such as high-powered harpoon launchers and explosive harpoons, both of which are standard equipment, kill rates are much higher. Also, instead of having a huge group of boats go after one single whale. One lone whaling ship can kill several whales on its own.
I conclude that whaling as a Japanese tradition can go on, but it should have the same kill rates as during the 8th century and the killing techniques used must be as humane as possible. A solution would be to have a maximum number of whales killed per year, whether their bodies are recovered or not and to have a team of International Whaling Commission members to verify so.
