Winter is cold. I know, LOL. Don't say "hibernation"! I want you to see it when it's beautiful.
Good evening
, it's Miiman
Winter is in full swing! It's already February tomorrow, time flies.
Tonight, it's been a while!
Current Izu information![]()

The water temperature might be lower than usual for this time of year! Is this because the Kuroshio Current's meander has ended?!
Current water temperature: 15-16℃
For several years, the bottom temperature in Izu had been a relatively high 16℃,
but lately, it's often dropped to 14-15℃![]()
Miiman's current drysuit undersuit![]()
In addition to the TUSA BODYX drysuit undersuit (top and bottom),
leg warmers and heat packs on my back and stomach.
I also put adhesive heat packs on my feet.
This is my gear for water temperatures up to 15℃.
If the temperature drops to 14℃, I add another full set of specialized undersuits to this setup.
And of course! I equip a 6.5mm hood & winter gloves
When wearing undersuits, everyone![]()
Instead of adding more undersuits when you're cold, it's better to equip yourself to prevent getting cold in the first place!
It's much harder to raise your body temperature once you're cold.
Because if you feel cold once you're in the water
, you won't be able to concentrate on your diving.
Of course, there's some stress from increased weight, etc.,
but if you switch to undersuits specifically designed for diving, the bulkiness and restricted movement are resolved![]()
I want you to fully enjoy the stress-free visibility
of the winter sea!

It's so clear you can see everything!.
Wide-angle photos are fun in winter too![]()
Visibility is 10-15m!
Now that the water temperature has dropped, all you macro lovers
have been waiting for this ♡

Nudibranch season has arrived![]()

The world of nudibranchs, often called "gems of the sea," is captivating once you get into it![]()
I want to guide everyone to the macro world! Welcome macro lovers![]()
For the past few years, the water temperature hasn't dropped much,
so we haven't been able to see lumpsuckers![]()

The baby with a halo is about 5mm

Their round form will steal your heart the moment you see them🫰
It’s a Small World ![]()

There are also creatures you can only encounter when the water temperature drops significantly![]()
Target month is March! I hope we can see them this year![]()
You'll definitely be moved and soothed by the transparent underwater world, which rivals even resort seas!
