Accessibility and Fiscal Stress in a Shrinking Hokkaido Town
Town A in eastern Hokkaido has 6,800 residents, down 27% since 2000, and 38% are aged 65 or older. Dairy farming and coastal fishing dominate the local economy. The only hospital is 55 km away. In 2015 the bus service was cut from six to two daily round trips. Abandoned farmland rose from 40 ha to 210 ha. A new expressway interchange opened 18 km away last year. Municipal tax revenue has fallen 19%, while road maintenance cost per resident is 1.8 times the prefectural average. The town must choose among (a) subsidizing the bus route at ¥38 million a year, (b) consolidating two schools and opening a small clinic in the northern hamlet, or (c) using the interchange to attract a food-processing plant. The mayor wants a decision within six months, before the national subsidy window closes.
1. Which data in the setup most strongly indicate an accessibility crisis, and what causal chain connects them? Explain in three or four steps.

Data selection. The strongest indicators are the 55 km distance to the only hospital, the cut from six to two daily bus round trips, and the 38% aged 65+ share. These directly measure access and need. Farmland abandonment and tax decline are consequences or context, not direct access measures.
Causal chain. (1) An aging population raises the number of residents who cannot drive. (2) The bus cut removes the remaining public transport option. (3) Carless residents must rely on family, taxis, or move away, so hospital visits and daily shopping become less reliable. (4) Out-migration of younger carers further reduces household transport capacity and tax revenue. The interchange is not a substitute because it serves through traffic and is 18 km away. The chain is plausible but not fully proven: the setup does not give car ownership, taxi cost, or actual missed-appointment data. Those would be needed before calling the bus cut the main cause.
2. Evaluate the three options using efficiency, equity, and long-term sustainability. Which would you recommend, and why?

Efficiency. The bus subsidy costs ¥38 million a year; if it carries, say, 20,000 riders, that is about ¥1,900 per ride, high unless it prevents costly institutional care. The clinic may reduce long trips and improve early care. The plant may create jobs but needs workers, water, and transport, and may not help the elderly.
Equity. The northern hamlet and carless elderly bear the greatest burden. A clinic plus targeted transport helps them directly; a plant may benefit landowners and younger workers.
Sustainability. A plant broadens the tax base but may demand infrastructure. A permanent bus subsidy is hard to withdraw. Consolidating schools saves money but increases travel for children.
Recommendation. A mixed package: open the clinic, replace the fixed bus subsidy with demand-responsive transport, and negotiate a plant only with a fiscal-impact agreement. This targets access, avoids a permanent high fixed cost, and tests the plant's claims. The choice depends on missing data: rider counts, clinic costs, and plant water and transport needs.
3. Explain why road maintenance cost per resident is high and how this changes the fiscal argument.
Read the worked answer
Road maintenance cost per resident is high because the town has a long, dispersed road network and a shrinking population. Many costs - snow removal, bridge inspection, pavement repair - are fixed by road length, not by users. When population falls 27%, the same kilometres are spread over fewer taxpayers. This is not necessarily waste; it reflects settlement geography and dairy access.
For the fiscal argument, per-capita cost is a warning, not a decisive number. If the town keeps all roads open, future costs will rise as the population ages. Consolidating the northern hamlet could reduce road length and service costs, but it would also impose relocation and access losses on residents. A better comparison is avoided future maintenance versus the one-time cost of consolidation and the clinic. The interchange could raise land values and traffic, increasing maintenance pressure rather than reducing it. The council should ask which roads serve essential dairy and emergency access and which are low-use.
