Settled in 56 A.S., Planet Honshu was the first colony in Kusari, after the initial colonisation of Planet New Tokyo. It bears a number of similarities to the Capital Planet, mainly in that it is an ocean world with few sizeable land masses. With so little land available for farming, the settlers turned to fishing as their primary industry. Unfortunately, very few Terran fish species took to the Oceans of Honshu, although tuna and salmon were among those that were able to survive. The Colonists struggled to feed themselves for several centuries, until overfishing caused a catastrophic decline in the fish stocks in 250 AS, which caused most of the inhabitants to abandon the planet and seek their fortunes elsewhere. The population dropped from roughly a 1.5 million inhabitants to 250.000 over decade that followed. Most emigrated to Planet Kyushu and it's vast rice farms, but others cast their eyes on the nearby Crow Nebula and the bountiful fuel gases therein. These Pioneers eventually became known as the Gas Miners Guild.
With the Colonists abandoning their ancestral home in favour of the Crow Nebula, Honshu lay fallow for over 250 years. Those that remained scratched out a meager living, trading what little resources the Planet had to offer with New Tokyo, and supplying the Gas Miners Guild with Water and Oxygen - both of which Honshu possessed plenty of. Eventually, in 510 AS, Kishiro Technologies decided that Honshu would be the perfect location to construct its main Optronics production facility, especially after planetary surveys revealed the oceans to contain significant quantities of various chemicals and raw materials that were useful in the manufacture of optronics themselves. Since the optronics factories could be built at seabed or on platforms, this has left a significant amount of the available land masses for the construction of towns and cities, and the population of Honshu has climbed steadily ever since, bypassing the 870 million mark at the latest census. Recent Honshu architecture closely resembles that of New Tokyo - compact, towering cities that economise on land use.
