What does this Treaty have to do with Ecchi Girls?

Question

In an email I got from JList talking about "ecchi girls" (their blog post), it talks about a Treaty of San Francisco

Then there's one of the most entertaining character types, the ecchi girl who can't think of anything besides sex, which -- in accordance with the 1951 Treaty of San Francisco -- must always be paired with a dull-witted male main characters who's unwilling or unable to take her up on her offers.

What exactly is this treaty? and does it really have so much control over anime in which all "ecchi girls" have to be paired with dull male character?

Answer 1

You have two questions here:

What exactly is this treaty?

and

Does it really have so much control over anime?

The Treaty of San Francisco they reference is otherwise known as the Treaty of Peace with Japan. Representatives from 51 countries worked together to create this treaty at an opera house in San Francisco, CA. The treaty was ratified by 48 of the 51 attending countries, including Japan, on September 8, 1951. This treaty marks the conclusion of World War II and the world's reorganization of Japan as an imperial power.

As far as its effects on the anime industry, this is merely a joke that J-LIST is making. The treaty has no effect on the anime industry. If you are interested in learning more about the treaty you can read the document itself on the UN Website^pdf.

I followed up with Peter Payne owner of J-LIST about your question and his response was:

It was just a random joke. That’s the treaty that officially ends WWII, so I pretended Japan was required to put dumb main charactors in all future harem anime to balance out the ecchi girls.
