| Title Alternative | Large-scale rainfall characteristics at the heavy rainfall event around the western Japan during 5–7 July 2018 |
| FullText URL | esr_032_033_044.pdf |
| Author | KATO, Kuranoshin| MATSUMOTO, Kengo| OTANI, Kazuo| |
| Abstract | Large-scale rainfall characteristics at the heavy rainfall event around the western Japan for 5–7 July 2018 were analyzed with use of the 10-mimute precipitation data at the surface meteorological observation stations of the Japan Meteorological Agency, and so on. In this case, the area with 3 days total precipitation of near or more than 300 mm was distributed widely from northern Kyushu to Shiga and Fukui Prefectures. As in the many heavy rainfall events around Kyushu District in the mature stage of the Baiu season, contribution of the intense rainfall with more than 4 mm/10-minute (24 mm/h) attained about one third of the areal mean total precipitation. However, it is noted that the "not so intense rain" with less than 2 mm/10-minute (12 mm/h) also contributed to about one third of the huge total precipitation in the wide area. In short, this case could be characterized by the mixture of the western Japan type heavy rainfall event and the eastern Japan type one. |

| Title Alternative | A trial of lesson practice at the university on the variety of heavy rainfall characteristics based on the 10-minute precipitation data toward promoting the meteorological disaster prevention literacy |
| FullText URL | esr_032_021_031.pdf |
| Author | KATO, Kuranoshin| |
| Abstract | In the disaster prevention education on the heavy rainfall around Japan, it is also important to promote the meteorological literacy on the seasonal and regional differences of their rainfall characteristics such as the convective rain or stratiform rain, together with their total amount of precipitation and their occurrence frequency. As the first step toward the above purpose, the present study made a lesson practice for the university students by utilizing the 10-minute precipitation data for the four heavy rainfall events, in which the types of the heavy rainfall (although all the cases examined in the lesson are relating to the deep convective clouds) are rather different from each other, such as the differences of the rainfall intensity at the peak time, short-period variation of the rainfall intensity and the persistency of the rainfall including the "not so intense rainfall". The reports by the students seem to perceive the different features among these events briefly, but the students' attention to how long the intense rainfall with short-period variation or "not so intense rainfall" lasted was not so sufficient. |

| Title Alternative | Petrological study of Sue ware from the Sabukaze kiln site, Okayama Prefecture |
| FullText URL | esr_032_009_019.pdf |
| Author | ANAMI, Taiji| NOZAKA, Toshio| KIMURA, Osamu| |
| Abstract | The Sabukaze kiln site, a representative ancient tunnel-kiln site in the Kibi region, worked during the Asuka period (from early 7th century to early 8th century) to produce Sue ware including jars, cups, coffins, and ornamental tiles. To determine the provenance of the materials used for the Sue ware, we carried out petrological analyses of 13 Sue sherds, including optical microscopy, X-ray diffractometry, X-ray fluorescence spectroscopy, Raman spectroscopy, and electron-probe analysis. In spite of the difference of production time, all the Sue sherds show close similarities in modal proportion of mineral inclusions with dominant quartz and feldspar, and minor volcanic glass, in chemical compositions of feldspar and interstitial matrix, and in whole-sherd chemical composition. These similarities suggest that the paste materials of the Sabukaze Sue ware were commonly derived from weathered rhyolitic rocks and obtained from the same or neighboring mining site(s) located near the kiln site. |

| Title Alternative | Microtremor exploration in Kojima Bay area, Okayama Plain |
| FullText URL | esr_032_001_007.pdf |
| Author | YAMADA, Nobuyuki| TAKENAKA, Hiroshi| |
| Abstract | This report describes microtremor array observations conducted at two sites for deep exploration and three sites for shallow exploration around Kojima Bay area in the southern Okayama Plain. Based on these records, the ground velocity structures were estimated. The results yielded solutions indicating the depth of the top of the seismic base layer (equivalent to 3 km/s layer) ranges from 140 to 300 m, while the depth of the top of the engineering basement layer (equivalent to 0.6 km/s layer) is approximately about 13–14 m. The shallow exploration results also suggested the possible presence of an inversion layer. These estimated velocity structure models provided a reasonable explanation for the observed phase velocities. |

| Title Alternative | Does Environmental Spending Reduce Firm Risk? Evidence from Japanese Companies |
| FullText URL | hss_061_155.pdf |
| Author | NAZIR, YUSRA| |
| Abstract | This study examines how environmental conservation costs (ECC) affects firm risk, using changes in leverage ratios and earnings volatility as stand-ins for risk. This study evaluates the direct impact of ECC and its relationship to profitability (ROA) using panel data of Japanese companies from 2010 to 2022 and Pooled OLS regression models. The results demonstrate the risk-mitigating function of sustainability investments by showing that, although independent ECC have little direct significance, their interaction with firm profitability dramatically lowers earnings volatility and leverage instability. These findings underscore the economic value of environmental strategies, suggesting that incorporating profitability considerations into sustainability practices enhances operational stability and reduces risk exposure. To help policymakers, investors, and corporate managers strike a balance between sustainability and financial performance, this study contributes to the growing body of research on the relationship between the environment and finance. |
