"Sōnan" (遭難, "A Distress"[1]), is the second single by Japanese rock band Tokyo Jihen, led by musician Ringo Sheena.

Tokyo Jihen was first formed in 2003, after Ringo Sheena decided on members for her backing band for her Sugoroku Ecstasy tour.

The arpeggio guitar introduction was thought up by Ryosuke Nagaoka (who would later become Tokyo Jihen's second guitarist, Ukigumo), as he recorded the song's demos with Sheena.

[8] The song's lyrics were written at the same time as she composed the music, and were not revised much from their original state.

Both releases feature an English language cover of an American song popular in the 1950s, and a B-side with a single kanji title.

[16] The video features the band's members in formal attire, performing the song in a theatre.

The video for "Dynamite" features Sheena performing the song cabaret style, with a troupe of backing dancers.

Listenmusic reviewer Kiyohiko Koike praised the single, saying the melody had a "good old sepia Shōwa Kayō taste", likening it to her earlier songs "Kabukichō no Joō" and "Marunouchi Sadistic".

[18] Reviewer Kyosuke Tsuchiya noted the song's "jazz-style approach", and was impressed by the "wild power" of Sheena's vocals and the "suspicious melody" created by the guitar.
