Turning Japanese

So I keep getting compliments on my pronunciation. Almost every other day I will have someone new respond to me in Japanese after an ohiogazaimus or konichiwa and then apologize, but my pronunciation was so good that I sounded fluent. Apparently, my year of Japanese in sixth grade rubbed off somewhere. It's making me really regret switching to Spanish, which I continue to lack any skill or proficiency at. Of course, it could also just be that I have a five word vocabulary in Japanese, which isn't very hard to master. But truthfully, it's the first time in my life that I have really wanted to learn a language, not out of necessity, but for the shear thrill of being able to say the words.
