Hi Azu. What a great hobby and future study. I love books too. Both because I love reading them, and also because I love them as objects (nice ones, of course).

Good luck with your studies! (And don't worry - your writing seems perfectly good.) Here are a couple of corrections - explanations at the bottom.

My first Notebook

Hello. I'm Azu.

I'm living in Tokyo, and I'm working at an office as an office worker,
sometimes working as an illustrator.

Actually I want to study conservation and restoration of books at a college in the UK in the future,
so, for now I'm studying English and bookbinding at home.

The Study of bookbinding is very interesting for me, but English writing is quite difficult
because I'm not sure that my writing is good or bad when I study it by myself.

Please help my writing!

You can say either "The study of bookbinding is..." OR "Studying bookbinding is..." Both have the same meaning.

This "for me" isn't really neccessary - it's clear from the rest that you mean you.

Wow, you're pretty serious about ramen!

Here are a few corrections:

Ramen Restaurant Nearby

Finally, I completed all 3 flavors in a Japanese ramen restaurant, which just recently opened. They did a special promotion until yesterday that offered a bowl of ramen for only $5 that included tax.

that included tax = including OR tax included

Since it's located nearby my home and I used to be a ramen freak years ago, I thought that I would be its regular customer, if it was good.

nearby = near my home OR nearby. (with 'nearby' the fact it's near your home is strongly suggested anyway).

After tasting 3 of the main flavors that they offer for now, I judged that this ramen restaurant would be able to compete with others in the future, but not for now. I mean it's potentially okay as a new ramen restaurant, but I can see its room for growth. Especially, for noodles. I want to find the ingenuity in the noodles, something elaborated.

but I can see its room for growth = and I can see it has room for growth (and works better here because room for growth would be considered something good - like being potentially okay).

Well, but it's okay, if it's promoted. It's worth paying more than $5.

It's okay = It could be okay (it seems like this is your prediction for the place, so could be shows you hope it will become okay).

Well, these are some pretty minor corrections. Overall it reads rather well and the meaning is very clear. Good job!

Wow, very advanced piece of writing, Yuuki. Some interesting points and questions. I can't really say I 'like' the internet either, but at the same time I keep using it more and more... I definitely agree with your point about 'knowledge'. When everyone is able to voice their opinion - or dress their opinions up as fact - it becomes difficult to separate real knowledge from quackery. If I want to find something out online, all too often I have to trawl through heaps of information before finding something I can trust.

Anyway...very good job overall, but here are a few corrections:

red = the meaning is not clear, I don't know how to correct this section
yellow = correction
green = grammar is fine, but could be rewritten for style / clarity

Hacktivism
Do you really like the Internet? To be honest, I do not like it. Mass people would say that the Internet was a revolutionary development in the human history. Do you really agree with it?

Mass = Most
was = has been (it's still true now - 'was' suggests it's finished)
it = that OR this

Real information, which educates you as a mature person, should be given to you from your community around. The communication lies at the heart of direct human experiences. The memory and experience become major sources for the meat and blood to make a part of us. On the other hand, superficial information on the Internet will make you feel comfortable temporarily with a great speed, but the comfortableness will rule your life style. I am now really having difficulty with controlling a life without computer knowledge. I wish listen to others with real contact and touch each single page to know something new or valuable to my life.

your community around = the people around you OR your local community
meat = flesh (meat is the word for animals, flesh for people)
the comfortableness = comfort
a life = my life (a life suggests YOU are controlling the life of ANOTHER person)
wish... = I want to listen to others, have real contact and...

The society should be equalized to the extent that we have advanced technology in every field in our daily life. Basic technology can be shared easily while innovation is a hard step, but what makes the spread of the advanced technology all over the world is politics. Controlling is easier for the people with authority or those who are in the position when the civilians are dumb. Technology, and source and amount of information is highly advanced as much as making the social gap among the people. So, rich people should be more engaging with organizing independent philanthropic activities. I am threatened by the need to keep up with the world of technology to fight against human rights. Knowledge and wisdom is the best weapon to protect yourself from the inequality and bring some peace to your community.

but what makes the spread... = but what allows advanced technology to spread all over the world is politics.
controlling = control
the = a
engaging with = engaged in (people should be engaging (verb) with sth OR people should be engaged (adj) in doing sth
is the best weapon = are the best weapons

Now we are getting to the highly advanced stage. Say, if you have a plastic surgery with nano-sized medical equipments inside your body, you will be able to get some kind of medical treatment to automatically and remotely. Or, those particles will be interacted with the environment where houses, furnitures, roads, transportations, and etc will respond to your command through the gadget equipped inside. This could be realized in the future because I as a mere citizen can imagine it. Then, take a look at the military weapons. It would take a couple of days to destroy the whole earth. Nobody would expect that, even extreme terrorists. So, we choose to control the situation with "politics", rather than destroy and take long time and damages to conquer the others. What is Human?

equipments + furnitures = equipment + furniture (non countable nouns)
will be interacted = will interact (active voice - it is the particles which 'do' the action)
the gadget equipped inside = an internal gadget

(Thank you very much for reading. Have a nice day there^^)
