Like the situation of alligator meat in US, vast majority of Japanese people have never eaten dolphin meat. The only place that the organized dolphin hunting is still happened is a tiny costal town, Taiji with only 3,000 residents out of 130 million (only 0.023% of the whole Japanese population) Dolphin hunting in Japan is just a local aboriginal culture. 　↓ https://youtu.be/voDLJB9Iwuo?t=4m49s　

Those dolphin activists always look down on the culture, make an insulting remark to the local residents, take a provocative attitude to the local police, behave outrageously and make lot of troubles for money (the rating of Animal Planet). This guy was refused entry because he has been recorded for a passport violation and reckless driving (without driver's license) in the past.
