Utsukushi shimajima

The Japanese colony on Uti/Gliese 33 are the "beautiful islands". These islands are a widely dispersed group rather than an archipelago

the major islands are:

Josho kame (rising turtle) controlled by Toyota

Kujira (whale) controlled by Sumitomo

Iruka to wakai (dolphin and baby) controlled by Mitsui-Sony

Tabeta sakana (eaten fish) controlled by Sanwa

Daibingu tori (diving bird) controlled by Dai-Ichi

Shinju no juzu (string of pearls) controlled by Fuyo

Government
The colonial government is a corporatised oligarchy whereby the each island is owned by a major corporate group (keiretsu) who are responsible for providing local government. Government officials thus also hold positions within the corporate heirarchy.

Colony wide governance is provided by the conference of elders (the corporate CEO's) with a representative of the Japanese Ministry of Trade and Industry sent from Earth to act as chairman and perform the largely ceremonial duties requiring a direct representative of the emperor.

Colonial relations
Generally isolationist except in a strictly commercial setting. most dealings are with American and Australasian colonies where relations depend on current corporate relations rather than being colony wide.

Military
Theoretically each island supports a proportional share of the colony's full spectrum of military capabilities. In practice these forces are a private army with only minimal control exercised by the colonial or Japanese government except in times of extreme emergency.

Due to regular low level military "dispute resolution" actions among the corporations, their special action forces are considered among the best in human space.

This continual low level activity also means distinct capability gaps have developed. None of the island's forces maintain the typical ratio of artillery or armour required under modern combined arms surface combat, relying instead on aerospace and UAV units for "heavy metal" fire support.
