The construction of protective infrastructure such as seawalls and the designation of land-use and building regulation zones are commonly recommended strategies for tsunami and sea-level rise oriented mitigation in coastal areas. While the effectiveness of these strategies are undoubted, in regions where coastal tourism is the primary industry, the implementation of such strategies have been low due to fear of negative economic impact related to loss of coastal view and accessibility. Therefore, this paper examines the influence of coastal amenities to hotel room rates alongside other attributes through hedonic analysis. Specifically, it investigates whether rooms with coastal views, accessibility to beaches, and those located on higher elevations are priced higher than other rooms, in order to quantify the associated values of Japanese coastal areas where tourism is a key economic driver. Subsequently, it suggests the geographical market boundaries to guide the management and risk-mitigation of coastal areas. Findings reveal that: Semi-parametric Geographically Weighted Regression (S-GWR) results can accurately identify both stationary and non-stationary relationships present between the dependent and explanatory variables; view of the sea and other environmental attributes have significant influence on hotel room pricings; and tsunami mitigation strategies which can have long-term implications should be adopted in a manner sensitive to the tourism industry.

对于沿海地区的海啸和以海平面上升为导向的缓解措施，通常建议采用保护性基础设施的建设，例如防波堤以及土地用途和建筑法规区的指定。尽管这些策略的有效性无疑是有效的，但在沿海旅游业为主要产业的地区，由于担心与失去海岸景观和交通便利相关的负面经济影响，此类策略的实施率一直很低。因此，本文通过享乐主义分析研究了沿海便利设施对酒店房价以及其他属性的影响。具体来说，它调查的是具有沿海景观，可通往海滩的客房以及海拔较高的客房，其价格是否高于其他客房，为了量化旅游业是关键经济驱动力的日本沿海地区的相关价值。随后，它提出了地理市场边界，以指导沿海地区的管理和风险缓解。研究结果表明：半参数地理加权回归（S-GWR）结果可以准确地识别因变量和解释变量之间存在的平稳和非平稳关系；海景和其他环境因素对酒店客房价格产生重大影响；应采取对旅游业敏感的方式采取可能具有长期影响的缓解海啸的战略。研究结果表明：半参数地理加权回归（S-GWR）结果可以准确地识别因变量和解释变量之间存在的平稳和非平稳关系；海景和其他环境因素对酒店客房价格产生重大影响；应采取对旅游业敏感的方式采取可能具有长期影响的缓解海啸的战略。研究结果表明：半参数地理加权回归（S-GWR）结果可以准确地识别因变量和解释变量之间存在的平稳和非平稳关系；海景和其他环境因素对酒店客房价格产生重大影响；应采取对旅游业敏感的方式采取可能具有长期影响的缓解海啸的战略。
