Why Japan funds more escorts than Britain

Japan treats protection of national sea lines as a direct force-planning requirement, while Britain has repeatedly assigned much of the same burden to alliances.

Question

Why does the Japan Maritime Self-Defense Force have more escorts than the Royal Navy?

Short answer

Japan counts sea-lane protection directly in its national requirement, while Britain relies more heavily on allies to share that mission.

Notes

Japan's economy depends on maritime communication, and the JMSDF is allowed to translate that dependence into escort numbers. British debates about the same requirement often move quickly toward allied commitments and burden sharing. That assumption reduces the number of escorts funded for the Royal Navy even though British trade is also maritime. Later Type 31 and Type 32 concepts reflect recognition of the gap, but recurring funding has not consistently matched the strategic requirement.
