Here are some pictures from field sites and every day life in the lab.


We set 300 nest boxes in the Tomakomai Experimental Forest, owned by Hokkaido University. Japanese tit (Parus minor) is the major species to use the nest boxes. About 15-30 breeding pairs use them every year.


A male Japanese tit brought a caterpillar to nestlings.


An amazing male masu salmon, developing strong secondary sexual characters. This guy migrated more than 200 km from the river mouth. Unfortunately, a high dam is now under construction in the Sanru River…


A typical meal during fieldwork – rice and canned foods. Everything is tasty in the field!!!


When we have a good research budget, we stay in a simple bungalow. But when we don’t, our hotel is … our car!


Dolly Varden charr, one of the main study species. Very pretty showing red spots on a blue or yellow background.


Urban red squirrels are also a main study species – they are really cute 😀
