It's not the strongest reason to marry I've ever heard.
I wonder if you aren't over-thinking this marriage thing. Perhaps it's better to just go with the flow and see who you meet along the way wherever you are (regardless of her eyes or writing system).
Good luck
Uhmm, well I put a map in front of me deciding a country to go (Philippines, Thailand, Taiwan, Brazil, Switzerland etc). I can't take the Marco Polo approach meeting women from every corner of the planet. So before getting causal with a lady, I should refine a lot of decisions while she's not involved in person.
For example: History of international marriages with guys from my country.
In Shanghai-China an American lady is living with her Chinese husband; she was insulted in English, beaten by a random passer by, got her arm bruised and police told her "you're lucky you didn't get hurt more, we can't do anything about it". A French guy's Chinese wife was stabbed to death in Beijing with a one-meter sword in public on August 2015.

From the last link, I just learned that the bride was from Shandong. Gives me a flashback to my Nanjing lab-mate who was a girl from Shandong (Probably we could be dating if my university wouldn't sent me to Suzhou)
I understand these tragedies don't happen on a daily basis; but a glance on my background shows that if there's a rock falling from sky, most likely it will hit my forehead. I think they were far more successful than me since they could make it up to a wedding; I feel very sorry for the Chinese newlywed. I may end up in prison in Japan for touching someone in train and be confirmed innocent 5 years later with a movie about it:

So, before I see a girl I should apply to a university. That's exactly the time I should decide which country.
Since I'm a lonely guy and I have free time during non-sleep hours, a language with 5000 different shapes is a cheap Play Station for entertaining me.
I also think best girls to date with are the local ones since I don't have to worry about them disappearing after graduation or asking me to fill their online application for Harvard. That means reasons of going to Japan initially are eyes and kanji + surprises
