The navy of the Japanese Defense Force now has more ships than the Royal Navy.
Oh...by far and away. And they have had for some time.
The JMSDF is arguably the 2nd most effective and largest destroyer navy in the World next to the US.
Their AEGIS destroyers and newer flat deck helo carriers and amphibious ships are very powerful and they continue to upgrade and modernize.
They do a lot of training as well.
They have over fifty modern destroyers.
