Now THAT is how you study English!

In Japan, hobbies are a serious business.

Making English Work / Study a 'hobby' for Shin-Idemitsu boss : The Language Connection : Features : DAILY YOMIURI ONLINE:

"Company Chairman Yutaka Idemitsu starts his day by studying English for an hour after rising at 5 a.m.--a practice that he has maintained for nearly two decades.

Using textbooks for NHK's English-learning radio programs, he copies the dialogues and their translations into notebooks and adds notes on featured words and idiomatic expressions. He then records his notes onto cassette tapes, and listens to his own "programs" before retiring at night or while taking a bath.

When his favorite programs weren't aired during his morning study time, Idemitsu used to listen to the CDs that accompanied the books. However, he gradually became dissatisfied with what the CDs offered.

...Now Idemitsu refers to the study of English as one of his hobbies. "It's just fun for me to study English as I always find something new," he said. "That's become part of my life. It doesn't even feel like I'm studying, really."

At the link you can read, basically, about his entire life history studying English, from NHK radio programs after WWII to the present day. It's pretty fascinating.
