A nice little article here from Japan Today a few months back. Very glad to see local English newspapers talking about the thing that we all know here in Shikoku. This really is such an interesting and marvelous place. When the restrictions for international travel are lifted and you are looking for a retreat to regroup and heal up a bit, Shikoku might be the place to get you re-centered. Take a few days and go for a journey around the whole region. Each prefecture has its own treasures for you to discover.
