Could a coal-fired USS Texas be supported in historical Japan?
Short answerPossibly during a stable period with sufficient coal supply, but factional politics and especially dry docking would still need to be resolved.
NotesCoal use for heating in northern Japan makes it another candidate for supporting the ship. Periods of stability are considered helpful because the supporting economy would need time to organise resources. The island setting is contrasted with continental states exposed to incursions across land frontiers, although Japanese factional conflict would still matter. Dry docking remains a serious unresolved requirement, so the answer supports Japan as a possibility without identifying a period when every need could be met.
