I hate to feed into the negativity and depression, but here goes:

This is another example of the Old Guard dying off, and no one rising up to replace him.

What young Japanese priest is rising up to fill the shoes of Fr. Nariai?

Too many elderly members (many of whom are pioneers) of the Trad movement are dying without any substantial, de-facto replacement that one could point to.

The one exception: we had Archbishop Lefebvre, then the 4 bishops, then Bishop Williamson, and when he passes to his blissful reward, we'll have the other 2 bishops and finally (at least) Bp. Zendejas who is substantially younger than the other 2. So that's one category we're "good to go" in.

But so many other categories...

I know of one Traditional chapel that was materially helped in the beginning by one elderly couple -- who were pioneers of the original Trad movement in the 70's as well. They both died (within months of each other) and frankly, there is no equivalent at the chapel today. The priest is making do, but to this day they don't have a e-mail chapel bulletin anymore. And if it weren't for the fact the chapel is fully equipped (and equipment lasts a long time!), they'd be in trouble there as well.

On the positive side --
If it's true we don't have a Tom Nelson publishing Trad Catholic books, the million dollar question is: Does 2020 need a TAN Books? Do people read books anymore? or do we need eBooks and digitized versions of public-domain pre-VaticanII books instead?

If ChantCD.com is still in business in 10 years, it will mostly be selling downloadable MP3s of chant and hymns, a few rare, hardcore Trad books, and eBook versions of such books. My son(s) will never have to learn how to hand-make the CDs, crease and slice cardstock for the CD inserts, etc. because CDs are going obsolete as we speak. So are magazines and newspapers. Books are almost in the same boat.

The Antichrist will censor Catholic truth and the true Bible in digital books. The only way to preserve the truth is in hardcopy transcribed directly from earlier texts in harcopy.

Impossible.

Only eBooks with "digital rights management" can be shut off, disabled, etc.
Many eBooks are DRM-free so as long as you have the file, you can read it whenever you want, on whatever device you want. Only a computer virus or hard drive crash could take it away from you (and it would be your fault in that case, for failing to keep a backup of the files)

That having been said, I admit that books are special. There's something about that physical connection with a book. It's so much easier to concentrate on the contents. eBooks are NOT 100% superior to a physical book. There are better in some ways, worse in some ways.

MP3s, however, are 100% better IN EVERY WAY than a CD of music. MP3s can be sorted into folders, copied/pasted if you want to hear one song multiple times in a playlist, easily make playlists, combine your favorite songs from X CDs, they take up less space, you can store hundreds of CDs on your PC, just a mouse-click away, complete random access, much easier to browse, no having to dig out physical CDs and insert them in your player, etc.

There are improvements like

CD --> DVD --> Blu-ray DVD
2GB RAM ---> 8 GB RAM ---> 32 GB RAM
100 MB Hard drive --> 1 TB hard drive --> 4 TB hard drive

Which are simply better in every way -- where the older technology is rendered completely obsolete and has no upside.

Phone books have no upside over Googling "Plumber (my city) (my state)"
Multi-day, regular Internet outages just aren't a thing in a 1st-world country like America. And in a collapse scenario or catastrophe, I don't think we'll need a phone book either :) 

He will find a way to censor and alter (distort true passages) texts of holy Catholic literature and the Bible in digital books.

Firstly, you are pulling that prophecy completely out of your butt. There is no basis, let alone references or proof, for such a belief. It is based on complete ignorance of electronics and computers.

I am a computer programmer with electronics knowledge as well. If the Antichrist could manipulate the bits of a microprocessor or microcontroller, which isn't even connected to the Net, from hundreds of miles away, then he could just as easily manipulate the pigment on a page of text.

Electronics aren't magic -- at least once you understand them.

Is the Antichrist going to manipulate the universal laws of physics? He's not God. The devil has angelic intuition, a complete grasp of the material world, but there are certain things he can't do (create life, raise the dead, etc.)

If I hook up a 5V source to a 100 ohm resistor and a 100 microfarad capacitor, the frequency of the resulting R-C oscillator will be a certain value -- Antichrist or no Antichrist.

Whose coming is according to the working of Satan, in all power, and signs, and lying wonders ~ 2 Thessalonians 2:9

He performs great signs, so that he even makes fire come down out of heaven to the earth in the presence of men. ~ Apocalypse 13:13

For false Christs and false prophets will arise and will show great signs and wonders, so as to mislead, if possible, even the elect. ~ Matthew 24:24

Yes, but you can't thereby conclude the Antichrist -- or the devil -- is OMNIPOTENT and can do anything he wants. Only God is omnipotent.

The devil isn't omniscient either. The devil can't predict the future choices of beings with Free Will, for example. He's a damn good guesser though.

Being able to spontaneously combust someone, or levitate in the air, is a superhuman ability, or prodigy. But the ability to work "wonders" or "prodigies" does not mean the devils are omnipotent. I don't believe devils can turn water into wine, for example.

The Church used to look into miracles very closely, to rule out the possibility of demonic action. The 2 miracles required to declare someone a saint, for example. They had to be something a devil couldn't do.

You can't take those vague, general prophecies from Scripture and embellish them as you have done. I asked for a basis for your prophecy that "the Antichrist will manipulate the contents of SRAM chips at a distance". You have failed to provide.

By the way, I don't know what your problem is. I've already said books are better in many ways. I have many bookcases full of them myself. I advise everyone to stock up on good Catholic books. But not for some silly made-up prophecy that a layman dreamed up.

As I am technically illiterate, do MP3's require electricity/batteries to function?

Japanese Priest Retired from Diocesan Ministry to Celebrate Traditional Latin Mass

June 25, 2013
A Latin Mass in Japan

by Christopher Pitsch

 Less than 1% of the Japanese population are Catholic. Hence, it’s no surprise that a Latin Mass is a rare bird in Japan. Fr. Ueda, a priest from the Institute of Christ the King Sovereign Priest, says a Latin Mass once a year. Fr. Onoda from the Philippines visits once a month.

There is, however, one priest in Japan who regularly celebrates Mass in the Extraordinary Form. In the midst of the impossibly overcrowded, hectic city life of Tokyo, Fr. John A. Nariai offers the Holy Sacrifice of the Mass in a small private chapel in his personal flat.

Fr. Nariai is a retired priest of the diocese of Kagoshima in southern Japan. He first came in contact with the Latin Mass in the year 2000, because he was an active member of the pro-life movement in the U.S. He often participated in the meetings and conferences of Human Life International “and out of the blue, a priest, a Father Richard sent me a 1962 missal. That was my first contact with the Latin Mass,” Father Nariai recalls.

 Father Narial fell in love with the old Rite. His Bishop refused to allow him to celebrate according to the old missal, but Fr. Nariai also refused to stop celebrating the Latin Mass. He had a long discussion with his bishop through his envoys and in the end he suggested: “What if I retire?”

The Bishop accepted and Fr. Nariai moved away to the huge metropolis of Tokyo, at the age of 67. “When in medieval Japan someone had to go into exile, it was called ‘miyako-ochi.’ I’ve done a miyako-nobori,” says Fr. Nariai proudly. “Miyako” is the Japanese word for “capital”, so, “miyako-ochi” means “kicked out of the capital,” while “miyako-nobori” means “ascending to the capital”, i.e. going to Tokyo.

Today, Father celebrates the Latin Mass every day, including Sundays, accompanied by his Japanese congregation singing Gregorian chant. Fr. Nariai’s lovely chapel is Japanese style, with shôji (japanese sliding doors) and tatami (mat made of rice straw). In a Japanese room shoes are prohibited, so the priest doesn’t wear shoes, even while celebrating Holy Mass.

(PERSONAL NOTE: For this reporter, this looked odd for a moment. But everything about the Mass was so dignified and beautiful, I began to see it as a rightly understood enculturation.)

About ten faithful regularly attend his Mass, mostly young people. It’s a small but lively and cheerful group, drinking green tea together after Mass, with inspiring conversation. When I joined with this community, I never had the feeling I was in Europe, though Catholicism in Japan is often seen as a European thing. The after-Mass socialization is not necessarily European or Japanese culture, its Catholic culture.

 “I have always wanted to be different from others; that was my motivation to enter the seminary. Now I’m again different from all the other priests in Japan,” Fr. Nariai explains. “But in fact, I don’t want to be different. I want every priest to discover the treasures of the Latin Mass.”

Despite his 78 years, he is very communicative and active and loves to come into contact with other priests and the faithful. He can be contacted on his web-site, too, at http://www.geocities.jp/fr_nariai/

For me, his Mass has been a great experience in Catholic culture. In Japan, I can actually feel that the Church is Catholic in the sense of “universal.”

Latin is the Church’s language; it connects people around the world. This Holy Rite of the Mass makes me feel at home, even in a very un-Christian culture like Japan.
Finally, the Mass provides a foretaste of the Glory yet to come.

Lord have mercy and grant him eternal rest.

May he rest in peace.

Eternal be his memory. Eternal be his memory. May his memory be eternal.
