Part 6/10:
Despite the promise of geothermal energy, development faces obstacles—such as concerns over the impact on traditional hot spring sources, which are finite and sensitive ecosystems. The risk is that overdevelopment or incorrect drilling could diminish the natural flow of hot spring water, impacting local livelihoods and cultural heritage.
Community-led initiatives emphasize transparency and mutual understanding. The local residents and inn owners advocate for thorough scientific monitoring, including installing IoT-based sensors to measure temperature, pressure, and flow rates of the hot springs. This data helps ensure geothermal development does not harm the longstanding onsen culture, fostering trust and acceptance among residents.
