Hello, I'm Kou from Taiwan.
Typhoon No. 8 is approaching Motojima, Japan.
Okinawa has little effect, and the weather is steamed and hot.…
There are a lot of explorers here today.
First of all, explain the expedition.
Well, take a group photo before departure,
Gogogogo to the cool cave
I got to the exploration route,
Lighting the headlight
Undeveloped cave area,
Beware of your feet
Speleothem on your head
It is NG to touch the white Speleothem, be careful
Review the name of Speleothem here
Pillars, bamboo shoots, pillars…Etc.
And enter the groundwater area
There was a lot of rain this year,
There's plenty of groundwater.
The place where the water is deep is about the depth of the adult's chest.
The water temperature is cool at 18 degrees
The ceiling was also lower.
Let's 
do our best, everyone
Challenge to the lowest ceiling.
A height of about 90 cm…Adults are hard
And taking an intermediate break.
Perform a dark experience
If you see something in the dark, keep it secret to others.
After a break, we will resume exploration to the second half of the race.
Guys, are you okay?
Next, the famous spot for exploring the cave….. 
"Straw Soda straws Full"
Because the white and thin Speleothem is dense,
A place where you can feel the wonders of nature
Entering the water area again
This time the passage is getting narrower.
But here is Speleothem like a coral reef…
Lots of "microgools"
Because of the Speleothem made of water flow
It's shaped like a wave
Don't worry,
Photos of the group in the last water area
A lot of Okinawa least horseshoe bat found near the exit
This is Okinawa least horseshoe bat, a food insect.
Small and cute~
Its name is "Okinawako-gashira bat"
Before the end of the exploration
I took a picture of the evidence that I escaped safely.
Thank you very much, explorers.
Thank you very much for your participation.
How about this underground trip?
So that you can be a good memory
Guide: It was E/Toyama.
