At the Laboratory of Aquatic Plant Ecology, we are interested in studying the ecology of seaweed and seagrass ecosystems. Every month, our team goes out into the field to collect samples and data using data loggers.
Japan is overcome with an abundance of herbivores, which has damaged coastal ecosystems to the point where almost no seaweeds or seagrasses remain. We are focused on understanding the process of isoyake ecosystem recovery.
Blue carbon is a relatively new term that generally describes the carbon that is captured by marine ecosystems. We are attempting to understand how this concept applies to a fisheries persepective and how to estimate the ability of coastal ecosystems to sequester carbon.
The future of seaweed aquaculture in Japan is unclear. We do not know how current practices of seaweed aquaculture will continue while climate changes progresses. We are interested in developing new crops and technologies to create a resilient seaweed aquaculture industry in Japan.

When sea urchins percieve a predation cue, they can move quite fast. If we can somehow alter the behavior of sea urchins, it might be possible to reduce their seaweed grazing rates. I hope to unravel this phenomenon and hopefully protect seaweed ecosystems.
Different environmental factors, such as water temperature and waves, are expressed in different species composition of seaweed communities in the subtidal zone. My research will examine ideas for optimizing seaweed bed restoration from a community ecology perspective by identifying suitable sites for seaweed to flourish and identifying seaweed species compositions that are likely to coexist.
I am studying the composition and distribution of marine litter in seagrass meadows. I am also collecting marine litter every month.
I am studying the blue carbon fixed by eelgrass beds in Omura Bay. If we can determine the area of eelgrass beds and the amount of carbon per unit area in the sea area under study, we can calculate the carbon storage in the eelgrass beds in the target area.
I am conducting research to evaluate environmental factors affecting seaweed communities in Arikawa Bay. In this bay, there is a difference in the species composition of seaweeds within a distance of 2000 to 3000 m. I believe that this difference, in a relatively small spatial scale, is mainly due to environmental factors.
I am evaluating the amount of carbon stored in the bottom sediment of an eelgrass bed in Arikawa Bay. To what extent do eelgrass beds on Nakadori Island function as blue carbon?
One cause of isoyake (i.e., the loss of seaweed forests) in Nagasaki Prefecture is the excessive increase and accompanying over-grazing by Siganus fuscens and Kyphosus sp. Thus, it is important to control the population of these fish. In Arikawa Bay, I am developing a technique to identify fish predators using camera traps.
I are investigating the optimum amount of carbon dioxide to be supplied to Ulva prolifera (suji-aonori) grown in land-based aquaculture. It is known that carbon dioxide supplied during culture increases the amount of growth. My objective is to determine the optimal amount of carbon dioxide for growth and to expand the from the culture scale to land-based aquaculture scale. It is hoped to develop a method of utilizing carbon dioxide emitted from industrial activities.
