Here in Indonesia, there's a lot of otaku community. Most of all otakus here know Utada.

In non-otaku/gamer/japanese related fan, Utada is quite popular among urban people. At least they know one or two of her songs (mostly First Love and Automatic). First Love is her most popular song in Indonesia. Nowaday, First Love album still avaible at certain bookstores or music stores.
Other songs like Wait & See, Sakura Drops, Can You Keep A Secret was also popular in 2000-2001, because tv stations played the PVs a lot. Some people who not into J music werere impressed with the PVs.
I remember in 1999 a nation wide tv station played Automatic pv, at that time she was the only Japanese singer that shown on tv. I didn't know how, then First Love gained huge popularity.
In Distance era, she included in some teen magazines, her posters can be seen in music stores, tv played her videos a lot.
But with she disappeared after DEEP RIVER, people were waiting for her next album but there was nothing, Utada busy with her Exodus. EMI Indonesia stopped promoting Utada. Then the popularity she gained with her 3 albums gone away. People forgot her and go to other singers like Ayumi Hamasaki, Boa. or bands like L'arc~en~ciel. People even didn't know about the Exodus when it released.
In 2006, ULTRA BLUE wasn't as succesful as her first three album, people found it very experimental and electronica, not what they expected for a japanese album.
2008, HEART STATION was maybe an album that can bring the 2000 memories back. But TOO LATE.People already find another stars.
