Not every dish needs to be everyone's cup of tea. This just leaves more of those who are seeking delicacies in a particular region or period in Japan. If you are visiting during the winter months, Japan is well known for the 'cod milt' dish that appears on menus. This is essentially sperm from male cod and the texture does not let you forget it.
Soft, white and kind of 'squiggly', this dish is generally eaten raw with a few mild seasonings or simply added to hotpot dishes.
If you are staying at an Otaru hotel such as the Grand Park Otaru in the winter, be sure to ask the staff for a good restaurant to experience this dish!
