Global warming scenarios have made the understanding of carbon sequestration changes in the stems of forest trees important. However, there is a lack of understanding about climate change's effects on the wood density of hardwood, which is a crucial indicator of wood biomass. Therefore, we...

The present study aimed to explore the dendroclimatic potential of three conifer species, viz. Taxus cuspidata, Abies koreana, and Pinus koraiensis, in the subalpine zone in the Republic of Korea. The tree-ring δ¹⁸O chronologies were analyzed for the last 50 years and were found to be well...

The so-called Millennium Eruption of Baitoushan Volcano is one of the largest of the Common Era but its date has been uncertain. Recently, Oppenheimer et al. (2017) reported the eruptive year as late AD 946 using a new method called carbon-14 spike matching. However, it is necessary to verify their ...

Among periodic patterns having origin in cambium and recorded in figured wood, the tangential waviness has been the first to be discovered and thoroughly characterized. Yet another pattern, manifested in the rippled surface of some tree trunks, has remained basically undescribed. This work is the...

Long-term temperature reconstructions are urgently needed to prolong meteorological climatic data, which are too short to evaluate the anthropogenic effect on climate change since the Industrial Revolution. The maximum latewood chronology (MXD) of Picea schrenkiana in the middle of the southern...

Hikobe House is an important cultural property located in Gunma prefecture. It is one of the oldest manor houses in the Kanto region of Japan. The age of the Hikobe House has up to now been uncertain. There are no architectural records or memorandum tags that indicate when the Hikobe House was...

Aim of study: To develop a statistical model framework to analyze longitudinal wind-damage records while accounting for autocorrelation, and to demonstrate the usefulness of the model in understanding the regeneration process of a natural forest. Area of study: University of Tokyo Chiba Forest...

The oxygen isotope ratio (δ¹⁸O) of tree-ring cellulose provides a valuable climatic record with an annual timescale. In Japan, the cellulose δ¹⁸O records have been accumulated over the past decade. However, no long-term records have been reported for the southern subtropical island, Okinawa-jima,...

This paper discusses a dendrochronological approach to studying works of art associated with Shintoism, an indigenous religion of Japan. Chronological studies of Shinto artwork are, by comparison, lagging behind the studies on artwork associated with the other primary religion of Japan, Buddhism....

The spring Arctic Oscillation (AO) significantly affects the subsequent summer rainfall in the East Asian summer monsoon (EASM) region, and analysis of meteorological data indicates this teleconnection strength varied on interdecadal timescales during the late 20th century. Tree-ring records may be ...
