Deep River

"Deep River" (2002) includes several major hit singles such as "Traveling," "Hikari," "Sakura Drops," and the title track "Deep River." The album debuted at number one on the Oricon weekly chart and became one of the best-selling albums in Japanese music history.

Yes, "Hikari" is included on the "Deep River" album. The song served as the Japanese theme song for Square Enix's original "Kingdom Hearts" (2002), and an English-language version titled "Simple and Clean" was used for international releases of the game.

"Deep River" was released in 2002 as Utada Hikaru's third Japanese-language studio album, following "First Love" (1999) and "Distance" (2001). It was one of Japan's top-selling albums of that year and continued Utada's streak of massive commercial success.

"Deep River" blends elements of contemporary R&B, J-pop, and acoustic balladry, with some tracks incorporating electronic production. This mix reflected Utada's genre-fluid identity established on her earlier albums while pointing toward the more experimental sound she would develop on subsequent releases like "Ultra Blue."
