To evaluate the effect of climate change on Japanese people\u2019s sense of seasons and this cultural ecosystem service, we examined the spatiotemporal variability of the flowering day (FD) of red spider lily at 9 sites (Maebashi, Choshi, Nagano, Kanazawa, Shizuoka, Tsu, Nara, Wakayama, and Okayama) over the past 60 to 70 years through its relationship with the autumn equinox. (1) Delaying trends were statistically significant (0.12\u20130.16 days per year) at 4 sites (Nagano, Tsu, Nara, and Wakayama). (2) Bayesian inference analysis with a beta distribution showed that the probability of FD being later than the autumn equinox has increased in the 2010s at all sites. (3) The year-to-year variability of FD was positively correlated with average temperature during the period of flower stalk elongation (late August to mid-September) at 7 sites (except Nagano and Shizuoka). These results suggest that the probability of FD being later than the autumn equinox will increase under further warming during the period of flower stalk elongation, thus affecting people\u2019s sense of seasons and this cultural ecosystem service.<\/jats:p>","DOI":"10.3390\/data11010009","type":"journal-article","created":{"date-parts":[[2026,1,5]],"date-time":"2026-01-05T16:07:07Z","timestamp":1767629227000},"page":"9","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Long-Term Temporal Variability of Flowering Day of Red Spider Lily (Lycoris radiata)"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0957-920X","authenticated-orcid":false,"given":"Nagai","family":"Shin","sequence":"first","affiliation":[{"name":"Research Institute for Global Change, Japan Agency for Marine-Earth Science and Technology, 3173-25 Showa-machi, Kanazawa-ku, Yokohama 236-0001, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4667-9736","authenticated-orcid":false,"given":"Taku M.","family":"Saitoh","sequence":"additional","affiliation":[{"name":"Center for Environmental and Societal Sustainability, Gifu University, Gifu 501-1193, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"199","DOI":"10.1266\/ggs.80.199","article-title":"Genetic variations in Lycoris radiata var. radiata in Japan","volume":"80","author":"Hayashi","year":"2005","journal-title":"Genes Genet.
