Realtime Generation and Translation of Japanese

Recently we took up the challenge of seeing how far the envelope could be pushed on learning tools for Japanese.

We’re delighted to announce real-time generation and translation of Japanese via our Composing Tool, Wag!

Old form of the Kanji “To Arrive” 来

Now, when students are composing sentences using Wag, Wag will attempt to translate the sentence and offer a grammatical interpretation of what was said. While it is far from perfect, it’s a huge milestone in generating Japanese and seeing a real-time English translation of what you’ve placed.

We hope to keep making incredible tools to help accelerate the learning process for Japanese! Check out a small demo video below:

Every time a sentence is submitted in the composing tool Wag, Wag will do its best to auto-fit a translation. It can do fairly sophisticated phrases (including use of “ands” and “of the’s”). We hope to make it available for public use one day. Right now, it’s available to subscribers of Japanese Complete.

Example generated translations with input:

The engine behind Wag can break Japanese into meaningful pieces and rearrange it to provide an English translation. Check out some of the real-time, actual results:

Imagine if while you were learning to write in Japanese, you could verify that you were meaning what you said, and saying what you mean. That’s what Wag does for Japanese learners. The functionality still leaves much to be desired, but it’s a very promising start for phrase-based translation and creative generation tools for language learning.

Want to Learn, Don’t know Where to Start

If you’re interested in learning Japanese and don’t know where to start, we have a free guide we released a few months ago in February called Essential Japanese: The Mental Model. It has a companion page to Reverse Engineer some elementary Japanese phrases.

Free Video Lessons for Learning Japanese

We’re delighted to announce that we will be offering free video lessons to learn Japanese. For our subscribers, these supplement the Japanese Complete curriculum, but they can also be used as standalone tools to help enrich one’s understanding of Japanese.

Here are the videos we have released so far. If you follow a video through to YouTube you can subscribe to get updates on new releases.

Wag: Japanese Sentence Builder

We created a new way for beginners to start generating native Japanese. It’s a tool we call Wag that also demonstrates, via state machine, which words are possible next in the sequence. The machine only allows you to submit a sentence when it’s grammatically valid. While it is not semantically aware (it’s not aware of meaning), this simple tool is capable of ensuring that words and their sequence obey the Japanese rules of grammar.

Below is a sample video to show a demonstration.

Wag: Japanese Complete Sentence Builder

You can generate a huge variety of Japanese with even a small set of common words thanks to its logical lego-block nature.

Wag is currently available to subscribers of Japanese Complete. Get a subscription today and start sharpening up your brain with a new language skill you can use for life!

Reverse Engineer some Japanese

We released an interactive toy of a page to help people break down Japanese Sentence Structure.

The page has also has informative tables to help scholars understand the major differences between the Japanese Complete approach to categorizing terms, compared with classical pedagogical methods for teaching Japanese.


Look for the buttons to engage each cell, for the examples are interactive!

An example of the Reverse-Engineer page example cells where the buttons make the examples interactive.

Additionally, our companion guide that you can use to start studying Japanese is completely free. While one needs a subscription for full access, you can still learn 120 of the most common Japanese words and the essentials for sentence structure with our Essential Japanese: The Mental Model, absolutely free.

Landscape of Japanese, 「Temple Visit」 Dialogue, Year Pre-Pay Plans

Landscape of Japanese: 3 Mountains, 2 Clouds, 1 Sun.

Discussion on the Landscape of Japanese and a link to our Essentials Guide: The Mental Model, is available below. We also introduced a year pre-pay plan where when you pre-pay for a year of access to the ultimate learning platform, interactive textbook, and ninja training grounds, you get two months free.

New Lessons and Dialogue Available

Today we’re excited to announce the release of new lessons and dialogue, “Temple Visit,” available with Audio Reading Tutor support so you can click and listen to the sentences as you follow along.

Listen along to the latest Audio Reading Tutor in “Temple Visit,” and get the most out of your Japanese practice time.

By getting your ears wet with real Japanese dialogue right off the bat, you’re preparing yourself for listening comprehension as well as generating spoken Japanese.

All of our dialogues are suitable for memorizing, giving you a wide array of immediately useful Japanese verbs, nouns, and phrases to help you tackle the needs of everyday life.

You can also jump between the Japanese, Japanese-Complete-English, and English translations of the material with ease!

Three Kinds of Translation

In Japanese Complete we have three kinds of translation to expedite the acquisition of Japanese:

  1. Native Japanese
  2. Japanese Complete English (Student Language, our custom hybrid)
  3. Native English

By using three translations side-by-side you can learn quickly what phrases mean and how to reason using your new Japanese brain.

We use inline explanations for some complex grammars that are taught later on.

Landscape of Japanese

We introduce a landscape of the Japanese language, master the three mountains, two clouds, and one sun and you’ve got a grip on all the fundamental topographical features of the language! Amazing!

  • Politeness language (social-language) Hierarchy shines like a sun that hits every aspect of Japanese culture and language in some way. Every sentence incorporates some version of politeness language.
  • Regional Dialects and Sound Effect Language sprinkle the landscape like summer rains. They can carry a lot of information and certain dialogues can be achieved completely using sound effect language alone.
  • Finally, we have the three powerful mountains of grammar: Particles and the Copula (da), Verbs and Nouns, and Bunsetsu Jars (which take Particles as lids) and Verbing-Nouns, a way to explain what a noun is doing by sticking a verb in front.

By mastery of the three main kinds of feature in Japanese we can quickly move along and achieve fluency in reading, listening, and eventually writing and speaking Japanese.

You can learn all about Bunsetsu Jars, the most frequent nouns, and the most frequent verbs in our free guide [pdf]

Our no-cost guide is called Essential Japanese: The Mental Model and is available by the above link.

You can get our free Mental Model for Japanese by the link above. It’s a free pdf covering the most frequent nouns, verbs, and bunsetsu jars as we teach them in Japanese Complete! A lot of great info in a free, 40-some page guide. We chant death-to-adjectives and for good reason.

Frequency Based Curriculum

The Japanese Complete curriculum is based on frequency. We teach the kanji according to their frequency distribution in the most comprehensive modern-day corpus available for Japanese (2011 BCCWJ).

Our curriculum teaches grammar, kanji, and verbs according to their frequency in real modern-day Japanese (including online Japanese like message boards, films, media, poetry, scholarly articles, and more). It’s an interactive textbook with resources, mnemonics, tips, tricks, and tactics to keep you engaged and inspired on your learning adventure to mastery.

Kanji Mnemonics and Calligraphy Stroke Order

Kanji are taught using etymological origins and clever mnemonics. The stroke order is taught and there’s even a way for one to check their kanji drawing in the character-recognition box. It’s not at all picky about stroke order, but it does help with memory and understanding. Being picky and disciplined with stroke order is up to you as the learner. It’s important to have proper stroke order if you wish to do beautiful calligraphy one day. Usually there’s good reason for the order, and if you imagine ink dripping down the wall like thick goopy paint it makes sense that some sequences would be better than others for drawing in blocks.

Kanji in English Context ™

Learn Kanji with a method specially devised for Japanese Complete in 2019, Kanji in English Context! See how kanji can mask some words partially and learn how they can be used to approximate a wide array of meanings. Kanji in English Context is your ticket to speedy and native-level comprehension of Japanese as fast, effectively, and efficiently as humanly possible.

“How to Say”

Check out “How to Say” and give our team of language experts a new question to ask!

“How to Say”

Early etymological character origins for “to arrive” 来 comes from an indicator / stand-in for collision point / center of a circle of arrows.

Bunsetsu Jars

Grammar explanations in Japanese Complete follow our simplified rubric that keeps the richness of Japanese near while avoiding many of the common stumbles and learning pitfalls when starting out. Initially, many courses overcomplicate things and include too much too ambitiously in the beginning. We stress frequency-based introduction to glyphs and words, as well as thorough practice so that identification becomes reflexive and second nature, step-by-step.

More Japanese = More Brain

Learning a new language makes you smarter (in some specific ways).

While these benefits are not exclusive to learning Japanese, because Japanese grammar is almost perfectly inverted to English grammar it’s likely that the benefits of second language acquisition are maximized.

  • Resist the onset of dementia entirely [1]
  • Solve whole classes of puzzles more swiftly [1]
  • Recognize and adapt to new information and new situations more swiftly [1]
  • “A heightened ability to monitor your environment” [1]
  • Make more rational decisions [2]
  • Improve your English (read: mother tongue) prowess and felicity [2]
  • Neuroplasticity (staves off brain aging) [3]
  • Increased Brain Gray Matter Density [3, 5]
  • Increased Brain White Matter Integrity [3]
  • Second language experience induces brain changes that can be found in children, young adults, and the elderly, and can occur rapidly with short-term language training. [3]
  • Procedural Memory and Conflict Monitoring (regions of the brain) increased in volume and density. [3]
  • Overall better situational awareness. [1, 3, 5]
  • Second language learning is a “Good way to keep the brain in shape” [0]

…Second language experience-induced brain changes, including increased gray matter (GM) density and white matter (WM) integrity, can be found in children, young adults, and the elderly; can occur rapidly with short-term language learning or training; and are sensitive to age, age of acquisition, proficiency or performance level, language-specific characteristics, and individual differences. [5]

“Language learning keeps the brain in shape.” 2012 Lund University

[3] Pushing the Limits of Neuroplasticity by Adult Language Acquisition (2017)
[3] Pushing the Limits of Neuroplasticity by Adult Language Acquisition (2017)

Gray Matter Density increases and White Matter Integrity increases thanks to language learning.

Increased Gray Matter Density and White Matter Integrity for age-appropriate language learning (even just a short duration) [5].
[3] Pushing the Limits of Neuroplasticity by Adult Language Acquisition (2017)

In praise of “age-appropriate input” [4]

(Age in Learning and Teaching Grammar)

Hosoda saw that increased gray matter and white matter density was maintained and kept by learners who stuck with language learning over time. Learners who had not kept up with “maintenance” lost the neuroplastic benefits gradually.

Short-burst language training with great frequency increases gray matter density and white matter integrity. For people who stop doing the language training, a year later their levels are back to pre-training levels. If you stick with the training and continue maintenance, the benefits continue to stick around.

Regions that show increased GM density/volume or CT according to a number of studies with group comparisons of
bilinguals versus monolinguals. Regions labeled with ** in the legend indicate bilateral GM; otherwise localized in the left
hemisphere or medial section. Further, structural increases in the specific regions are shown to be correlated with
behavioral tasks or variables: (þ): positive correlation with a task or variable; (¡): negative correlation with a task or
variable. These brain-behavior correlations are based on the following studies:
1 Abutalebi et al., (2012); 2 Abutalebi et al., (2014); 3 Klein et al., (2013); 4 Mechelli et al., (2004); 5 Ressel et al., (2012); 6 Pliatsikas et al., (2013); 7 Zou et al., (2012). [From citation 5 below ]

Various research is gathered here from within the last 20 years to show the overall consensus that brain density and volume are positively affected by language learning. Take for example this excerpt that explains how the functional networks each required for different aspects of language are tethered together, resulting in better neural connectivity:

[6] supports the brain scans that show better density and cross-linking between relevant functional parts of a language learner’s brain.

Audio Reading Tutor, New Story Arrives

We’ve added a new story to the Japanese Complete lessons library to help learners quickly assimilate spoken and written Japanese in tandem. You can listen along to the whole dialogue in one go, or click on each sentence to listen to how it sounds.

In addition, we have a method we devised specifically for unparalleled celerity in learning assimilation, Japanese-Complete-English or Student Language:

And finally we offer a thorough English translation of the story to help learners begin to see the correlated sequence for fluent Japanese and English translation and interpretation.

It’s quite a delight to listen to the dialogue over and over again with the aide of the Japanese-Complete-English (Student Language) and the English translation nearby, it improves recognition and assimilation rate substantially. In theory, the nonconscious mind is accepting Japanese more readily as it is blending with familiar language structures.

You can get access to the new stories and more by getting a monthly subscription to Japanese Complete. Invest in yourself and your brain by mastering a new language with Japanese Complete.

Introducing “How to Say”

At Japanese Complete we are striving to invent the future, and sometimes that requires using tried-and-true solid foundations of the past.

We are introducing How to Say, our new “search engine” for how to say anything in Japanese.

When you search for a new term, we add the term to a wishlist. Someone on our team will handcraft a result page for this query.

It’s kinda like made-to-order search results. Granted, there is a delay between when you ask for it and when it shows up, on the order of 1000-2000min instead of 1000ns like google, so we have a long way to go before it’s fully automatic and fast.

Scholars subscribed to Japanese Complete have priority access for questions, so their requested results get created first.
