I know you didn't ask to me, but the answer is: Mori Tower (Roppongi Hills)

As usual good progress, can't wait it reach the 300 meters!

It means something like:

"Yes! ! Five things are going and when you go to Tokyo Sky Tree travel more than 300m in January"

It is designed to withstand earthquakes which have destroyed Tokyo in the past. The tower is an articulated tripod of latticed steel pipes and a central concrete and steel core. An all-concrete tower would likely not survive a major quake without so much steel reinforcing that you might as well build with steel to begin with.

This is a 100% steel structure, isn't it?

Officially the tower is constructed with steel and reinforced concrete, but I think the foundation is the part of the tower where most of the concrete is used.

Does anyone know how the construction makes it safe in earthquakes? I want to understand how you can make a tower like this safe.

According to CTBUH, TST is a steel structure; not concrete, nor composite (concrete & steel). So, concrete shouldn't have any primary structural function here (letting foundation apart):

question: what about the core, is it going to have something similar to a mass damper to counteract the earthquakes.

Looking at those fantastic pictures from Momo, it JUST CAN'T be only 1/2 it's final height! It is SO much taller than anything around it.
