[Machine Translation] The two albums of "Yakusoku" (Promise), Type C and Type D, are released at the same time, each containing lyrics newly written by Takuya Nakazawa, a first under his name! The two songs are a fresh and exciting summer song and a sad and bittersweet love ballad, and both deliver Takuya Nakazawa's worldview in full! While he has been active in the media as the host of a major music program, his single "Yakusoku (Promise)" was released to much media attention and reached No. 1 on the Oricon Enka/Uta-uta Ranking. The arrangement of the coupling song for both types was written by Masayuki Sakamoto and Takuya Nakazawa, which greatly expands the world view of the lyrics, and the songs have different charms, making them a must-listen item for fans. The coupling song for Type C, "Summer Dreamer," is a refreshing summery song that will make your heart skip a beat.
