The base restrictions limited new fortifications and expansion in specified Pacific possessions, constraining Japanese forward-base development while also binding Britain and the United States. Japan had argued that additional bases were necessary for counter-piracy, but British and American participation weakened that case. The treaty sought reassurance by freezing facilities rather than removing every regional rivalry. Regular naval visits therefore served more than ceremonial purposes. They supported presence, observation, and confidence that rivals were not quietly changing the agreed status quo. Treaty verification was bound up with the everyday movements of cruisers on station.
