Shōwa no Kaidan Vol. 1 (昭和（しょうわ）の階段（かいだん） Vol.1, lit. "Shōwa's Stairway Vol. 1") is the first cover album by Japanese singer Shizuka Kudo. It was released on October 30, 2002, through Extasy Japan, marking her last release with the label. As the title evokes, the album features a selection of songs from the Shōwa period. It includes covers of artists such as Hiroko Yakushimaru, Mayumi Itsuwa, Kenji Sawada, Naoko Ken and Yōsui Inoue, among others. Kudo also recorded Japanese covers of "Moliendo Café", first recorded by Mario Suárez, and "Tennessee Waltz", originally recorded by Patti Page. The songs were originally covered in Japan by Sachiko Nishida and Chiemi Eri, respectively.

Kudo was praised for modernizing popular songs from the Shōwa period and for her more personal song choice.^[1]

Shōwa no Kaidan Vol. 1 debuted at number 66 on the Oricon Albums Chart. It charted in the top 100 for a sole week, selling a total of 5,000 copies.^[2][3]
