Well, some Filipinos stated it below. However, I have an additional here:

1. Some random indie-rap artists copy first love and include it in their recording.

2. Local TV Stations play Hikki's songs in their show. Particularly, in ABS-CBN where I heard 5 of Hikki's songs played in Kim Chiu's 18th birthday, and also in the local reality tv show Pinoy Dream Academy
, Prisoner of Love was played as background music.

3. Traveling, Automatic and First Love was played on the radios during the 90's.

4. In the segment top 5 of Myx, Hikki was once featured. They included her works from First Love to some tracks of Ultra Blue. (This was years ago)

5. The most famous Japanese song here (aside from the theme song of Voltes V and Pizzicato Five's Sweet Soul Revue) is First Love.

6. The only Japanese artist whose albums are sold here, is Hikki.
