I've been on a whale watching tour!
A lot of whales come to the Ogasawara Islands at this time.
Humpback whale parenting & breeding season is coming.
The Ogasawara Islands are famous for whale watching in Japan!
On Hahajima, there is only one boat that tours.
Therefore whales come in peace.
I was excited because there were many jumps that were the purpose of whale watching
The whale watching tour I participated this time
This is planned by Dive Resort Hahajima.
Usually it is a shop specializing in diving
Since it is a special tour only for the humpback whale season
Why don't you join us at this time?
See the following website for confirmation.

It will be more fun to remember, so learn the skills of whales!
・Blow
The act of squirting at the time of breathing.
Adults come up to breathe about every 15 to 20 minutes.
・Peduncle Arch
Behavior seen just before whales start diving.
Start diving while keeping your body high above the water surface.
・Fluke-up
The action of raising the tail fin when diving underwater.
At this time, the pattern of the tail fin is different for each individual,
Used to identify individuals.
・Tail Slup
Named from hitting the sea surface with a tail fin (tail). Shake straight down with the raised tail fin and slam the water surface vigorously.
Perform when threatening other whales, such as notifying your whereabouts.
・Pec Slup
Turn your body sideways and hit the chest fin against the water.
It is also used for whale-watching actions, such as when you are relaxing, or when threatening.
・Head Slup
The whale's upper body jumps out vertically and the head (mouth side) is hit against the sea surface.
・Spy Hop
The act of lifting the upper body vertically and leaving only the face from the sea surface.
Action to take when looking around and checking around.
・Peduncle Slup
The action of lifting the lower body above the sea surface and hitting it against the sea surface.
A sight seen when a male threatens another male or when competing for a female.
・Breach
Whale dynamic big jump! !
Lift a large body into the air, twist the whole body as it is,
Drops with big splashes.
The biggest purpose of tourism.
Most people will take a tour to see this moment.
The whale behavior observed during this whale watching (2 hours) was Blow, Peduncle Arch, and Fluke-up
Pec Slup, Head Slup and Breach.
What I couldn't hear from this time was the humpback whale's singing.
Humpback whales are said to sing songs unlike other whales.
It is said that male humpback whales sing during the breeding season.
The reason for singing has not been elucidated yet, but it is said that this is courting behavior against females.
Divers may be able to hear this song.
I need your help.
Please register to make the channel famous.
