Rausu : Where the Killer Whales Gather

The 2021 Report from the Summer Season is here! Written by Shiretoko Serai (Our guesthouse in Rausu)’s Nature Guide, Kaito Imahori.

♪　♪　♪　♪　♪　♪　♪　♪　♪　♪

There were more than 100 Killer Whales that visited Rausu. The Nemuro Strait, located between Rausu and Kunashiri Island, has had multiple families of whales visit every year starting from around May, to the end of July. The latest research suggests that the Nemuro Strait, may perhaps be a meeting place for the different groups so they can look for future partners.

This is a resident pod that is fishing together, which have downward pointing white patches around their eyes.

In the beginning of June 2021, I was able to observe a significant and amazing sight! We found a family pod of three mothers with a newborn child, near Rausu Port. While running side by side with this group in the sightseeing boat, I saw many unusual behaviors, such as a mother swimming upside down to feed her baby breast milk, just near the boat.

I also encountered another great scene this year. It was in mid-June, when I could see a gathering of 4 family groups at once, perhaps they were in the process of mating, but the males were swimming upside down with their penis out, courting the females from the other pod.

Even though I could not capture it in a photo, there was also another event worth noting that happened in late July. There were 2 white killer whales, a male and a female who appeared at the same time, which became major news. There are only a few places in the world where you can observe whales so closely, but it is because so many whales gather in Rausu, that you might see such unique and rare scenes like these.

Rausu’s Drift Ice Cruise and the Drift Ice in the Port of Rausu・The Steller’s Sea Eagle and White-tailed Eagle

This is a winter report from the Shiretoko Peninsula, Rausu (Hokkaido).

This year the drift ice season in Rausu was very short. The morning we arrived in Rausu, the staff at the lodging, Shiretoko Serai informed us right away, “Until last night, the conditions for the drift ice were very good, but the westerly wind is blowing, so its possible the drift ice might be gone by night time.”
Due to the strong winds, the dawn cruise was cancelled, but luckily we could get a 9am cruise where we could see the Port of Rausu full of drift ice.

This is how it looks in the Fishing Port of Rausu with the accumulated Drift Ice. There are Steller’s Sea Eagles and White-tailed Eagles feeding in the photo. If one takes the photo zoomed in, without the port in the background, you can get surprisingly great photos that make the eagles look like they are in a very natural spot.

Winter in Eastern Hokkaido, Rausu. Drift Ice Cruise and the Steller’s Sea Eagle

The Drift Ice Cruise of Rausu, Hokkaido. This year the drift ice arrived in Rausu around mid-February. This is a photo from a Drift Ice Cruise on March 5. From the day before, it was windy, and the drift ice moved towards the cape on the Shiretoko Peninsula.

We had chartered our boat for the Saiyu Travel’s “Photography Tour of Eastern Hokkaido in Winter” and we headed to sea in our Boat “Ohwashi.” The captain told us, “The drift ice has moved quite a bit, but let’s go check it out. If we travel for about an hour, we will be able to see it probably.”

Just before daybreak, we could see Kunashiri Island (Northern Territory, an island effectively under Russia) we could see a Steller’s Sea Eagle on the ice.

It’s Daybreak.

Sunrise with Kunashiri Island, the ice, and Sea eagles. The morning in Rausu is so breathtaking.

The surface of the sea had shards of ice floating and reflecting the sun like pieces of glass.

The mountains of Shiretoko as a backdrop to the Steller’s Sea Eagle.

The Sea eagle flying to the sea.

The sea eagle locked on to a fish.

The Sea eagles hitch a ride on the floating drift ice off the coast of Rausu.

Once a Sea eagle catches a fish that is thrown from the boat, it flies away. Then another bird will appear to fill the vacant spot.

The remaining bits of drift ice offer a precious place for rest, and they are competing for space on it.

The Steller’s sea eagles eating their fish on the drift ice.

Our boat ran to the Cape Shiretoko and we could finally see the massive drift ice collected there! Steller’s sea eagles were also sitting there as well!

From here on, there is nothing but drift ice. It looks like maybe it continues all the way to Kunashiri Island.

A Stellter’s sea eagle on the drift ice. Then, we heard from the captain, that the wind and waves were getting stronger, so we will turn back here.

The sea of Rausu in the early morning. It was a spectacular time with the Steller’s sea eagles and gulls doing their dance on the drift ice.

Winter On The Notsuke Peninsula, The Freezing Rain and Ezo Sika Deer

In February, the Notsuke Peninsula had an ice storm. When air temperatures drop below freezing and the ice rain, water droplets are super-cooled and ice can form on impact with the surface like trees. This ice from the freezing rain will cover and harden any exposed surfaces to make a clear ice called glaze ice. On the sunny days, when the sunlight reflects off the glaze ice, it can be so beautiful.

Glaze ice on the branches of the trees.

It is like being in an art gallery.

The branches covered in glaze ice.

An Ezo sika deer in the early morning ice.

The winter sika deer are looking so soft with their hair puffed out. Especially their fluffy white butt is so cute.

A herd of Sika deer on the Notsuke Peninsula covered with the freezing rain.

After dusk, the herd of male sika deer appeared in the field of snow and ice. It was a beautiful sunset, and I stayed there to watch until it got dark.

Beyond Cape Shiretoko: Mother and cub brown bears of Shiretoko Peninsula

On a nice calm day, with no wind or waves, we cruised from Aidomari around Cape Shiretoko in search of brown bears just before Rusha river in Shari town.

Now we are starting to see Cape Shiretoko! While on the cruise, depending on the location, the weather and conditions can change suddenly with wind and waves. On this day, Shiretoko was “stable”, but there was some waves along the way, since we were on an extended cruise.

This is the Shiretoko Misaki lighthouse. After passing that point, we entered the Sea of Okhotsk where usually there is a significant difference in the sea conditions between the Rausu and Shari sides, which are separated by the Shiretoko mountain range. However, it was a calm and sunny day on both sides.

The Cape Shiretoko has a plateau at 30-40m high, but the vegetation there was cut in the pioneering days, has never returned. There is also a factor that the Ezo-sika deer population has increased too much and is ruining the vegetation. The area from the central part to the northern part of Shiretoko Peninsula became a national park in 1964 and was later designated as World Heritage Site in 2005. Currently power boats are not allowed on land, but you can observe the landscape and wildlife from boats along the coast.

Same as on the Rausu side, there are abandoned fishing houses “banya” along the coast on the Shari side as well. The terrain on the Shari side makes it much more challenging for humans to reach.

Found them…the Brown bear mother and her cub.

The cute scene of a baby bear trying to keep up with the mother bear.

This little cub is just as curious about us. Since we perhaps were catching their attention too much, so we moved away from the coast and made our way towards the mountains.

Another pair of bears. This mother had walking with her a very young cub.

The mother bear makes her way up the slope while eating grass. And two little cubs trying to keep up.

Looks like they are a bit worried about the boat, and I apologized to them for interrupting them.

Pink Salmon Swimming Upstream : Autumn on the Shiretoko Peninsula

Pink Salmon, called “Kurafuto masu” in Japanese, return to the rivers on the Shiretoko Peninsula. These salmon came from the rivers and migrated out into the Northern seas for about two years; then return to their natal rivers to spawn.

These salmon just in front of me are on the verge of death. The Pink Salmon embody the very raw ‘act of living’ in their tattered appearance. We, who eat these salmon, must have gratitude in our hearts.

Salmon Run- Pink Salmon Going Upstream in the Fall in Shiretoko Peninsula

Compared to other salmon species, the Pink Salmon do not have a strong “Homing Instinct” and will swim upstream of any freshwater rivers nearby. In the year this video was filmed (2016), the peninsula had experienced 3 typhoons in mid-August. This had caused the salmon net that had been set along the coast to come loose, and it enabled a large number of salmon to make it upstream.

Pink Salmon that were caught in the net.

This is the mass of Pink salmon gathered at the bottom of a waterfall. Their dorsal fins are sticking out from the surface of the water.

Shiretoko Peninsula – Brown Bears Catching Pink Salmon

In late August, the Shiretoko Peninsula sees the return of the Pink salmon. However, due to a lack of rainfall, the rivers are too shallow for the salmon to swim upstream. As a result, the fish gather along the shore, in the sea, near the mouth of the river.

This is where the Rausu fishermen set up their nets, as do the brown bears, in the same area. This is the time of year when the brown bears are the most hungry and thinnest. The bears will venture into the ocean to catch the pink salmon that cannot enter the river.

This is the scene near “Pekin-no-hana”, on Shiretoko Pennisula with the fishing brown bear. It is like the White-tailed eagle is sitting just behind the bear, as if saying “Hurry up and catch something!” As the bear heads into the ocean…

A bear in the sea water.

The bear dunks its head into the water over and over, while swimming, to look for the Pink salmon underfoot.

It caught a female Pink salmon!

The roe, fish eggs, started overflowing with every bite.

It is probably too tiring to keep swimming while eating, so the bear heads back to the beach. It was there for a while, munching on the salmon with its backside facing us. After finishing off the main parts, the bear heads back into the sea for another round.

The White-tailed eagle quickly moves in to secure the leftover food. Then the crows move in for some leftovers too.

Then, just when we thought this bear would return to fishing, it got distracted and started playing with the net buoys! This must have been a young bear that was still holding on to its playful nature. Our customers who were with us, really enjoyed watching the fun-loving cute bear.

Eventually, it tired of playing and returned to the beach. It was a lovely chance to catch the last moments of summer with the brown bear.
