二代目米川敏子's '春の海' came out on November 25, 2015. Since 春の海 is still less than 10 minute long, it is still considered a pretty long duration song compared to the average song length. This song does not appear to be explicit due to the lack of the "E" tag. There is only one song in 聴く!日本のお正月~春の海・越天楽~, so we believe that "春の海" is a single. 春の海 is not that popular right now. Although the tone can be danceable to some, this track does projects more of a negative sound rather than a postive one.
