Based on my research, he did not actually go to Somalia, but rather to the neighboring Republic of Djibouti.

At the time, Somalia was extremely dangerous and under strict travel restrictions.

Therefore, he established a base in Djibouti, which was relatively safe and hosted a Japan Self-Defense Forces base.

He then invited former pirates and fishermen from the surrounding areas to that location.

In reality, his approach was to provide indirect support through fishing equipment and technical training.
