I'm a native Japanese speaker, who are learning English, but I'm not sure what other Japanese women think about it. As for me, I basically prefer talking to women. Also, I prefer doing voice chat, not video chat, because I'm a bit shy and I would feel more comfortable without a camera. To be friendly, to be able to speak your language slow and clean if necessary, and to be patient are important keys to become a good language exchange partner no matter which language you're going to pursue, I guess. So, your being a woman is already a big advantage! In addition, you're interested in Japanese culture. I'm sure you can make a good start. Just give it a try! May　I give you some corrections? 日本女性はどんな英語の話す言語パートナーを求めていますか？ =>日本の女性は、英語を練習する（言語交換）パートナーとして、どんな人を求めていますか？ 言語パートナーがほしいが 、いい言語パートナーになるために何すると知らない。。。 ＝＞言語交換パートナーを見つけたいですが、良い言語交換パートナーになるために、何が必要かが分かりません。
