SPACE ONE CO., LTD. (Japanese: スペースワン株式会社, Hepburn: Supēsuwan Kabushikigaisha, Corporate Number: 8010401132607^[1]), or Space One (スペースワン), is a Japanese aerospace manufacturer, orbital launch service provider, and spaceport operator. It is a private spaceflight company developing and operating the KAIROS orbital launch vehicle for small satellite launches; KAIROS flew its unsuccessful maiden flight in March 2024.^[2] The company was founded by investments from Canon Electronics [ja] (a listed subsidiary of Canon), IHI Aerospace (a subsidiary of IHI Corporation), Shimizu Corporation and the Development Bank of Japan in July 2018.^[3]

Rockets[edit]

The namesake of the KAIROS rocket, or Kii-based Advanced & Instant Rocket System,^[4] is the Greek word Kairos, which means 'time' and is also an alternate spelling of the name of Caerus, the Greek deity of luck and opportunity.^[5]

Launch site[edit]

Shimizu Corporation constructed Space One's own launch site for KAIROS, named Spaceport Kii, as Japan's first-ever private sector spaceport, in Kushimoto, Wakayama, Japan between 2019 and 2021. The launch site provides access to various orbit inclinations.^[6]

This spaceport is accessible from Tokyo International Airport (Haneda Airport) via Nanki–Shirahama Airport in approximately 2 hours and 20 minutes, and from Kansai International Airport in approximately 2 hours and 30 minutes.^[6]
