Hello!
I've wanted to learn japanese for a while, but I struggle to be persistent with it, lose my progress and basically always start anew.
So I thought if I keep track of my learning here and maybe even find someone who wants to learn with me (or someone who speaks japanese and wants to learn english or german in exchange?) it'll be easier for me to push through.

Without further ado, let's start with the basics.

Japanese consists of 3 writing systems:
Hiragana - Katakana - Kanji

Hiragana and Katakana are basically "the alphabet" - meaning there are each 46 characters you build your words with. Characters from Hiragana and Katakana have the same pronounciation, however you use them in different occasions.
Kanjis are the very complicated looking characters, originated from chinese symbols - one Kanji is a whole word. All 3 systems are used daily and are important to master japanese.

The first, third and fifth character are Kanjis, the rest is Hiragana

However Kanjis can be exchanged with Hiragana and reverse. To replace Hiragana with Kanjis is a way to shorten the sentence and to write less characters

On the top you see the matching Hiragana for the used Kanjis

For the first lesson, let's learn Hiragana:

To break this chart down, I'll start with the orange part on top.
Those are the basic syllables, the others (yellow and green) are addidional sounds.
We have 5 vowels, in the pic on the far right in orange:
あ - A, い - I, う - U, え - E, お - O

and basically everything else is a combination of a consonant and one of the vowels
so we have the K-row: か - KA, き - KI, く - KU, け - KE, こ - KO
S-row: さ - SA, し - SHI, す- SU, せ - SE, そ - SO
T-row: た - TA, ち - CHI, つ - TSU, て - TE, と - TO
N-row: な - NA, に - NI, ぬ - NU, ね - NE, の - NO
H-row: は - HA, ひ - HI, ふ - FU, へ - HE, ほ - HO
M-row: ま - MA, み - MI, む - MU, め - ME, も - MO
R-row: ら - RA, り - RI, る - RU, れ - RE, ろ - RO
exceptions are the Y-row and the W-row, who don't have a syllable with all the vowels
Y: や - YA, ゆ - YU, よ - YO
W: わ - WA, を - WO

additionally there's an extra character: ん - just pronounced as N, without a vowel
Please also notice the pronounciations marked in bold - they differ from the usual pattern.

In the yellow box are diacritics.
They consists of the K-row, S, T, and H.
All the K syllables with 2 little marks change in the pronounciation to G,
S changes to Z, T to D, and H to B sounds.
Exceptions: じ - JI, ぢ - JI, づ - ZU
Additionally the H-row with a little dot next to it, changes to P sounds.

Lastly the green boxes. They contain combinations of syllables with a fusion of the pronounciation.
The last part is always the Y-row, the first part are the syllables with I. The I sound basically disappears in combination with a y-syllable:
き/ki + や/ya = きゃ/kya
ぎ + や = ぎゃ/gya
し + や = しゃ/sha
じ + や = じゃ/ja
ち + や = ちゃ/cha
に + や = にゃ/nya
ひ + や = ひゃ/hya
び + や = びゃ/bya
ぴ + や = ぴゃ/pya
み + や = みゃ/mya
り + や = りゃ/rya

The same goes with the other two syllables of the Y-row. Also notice that the y-syllable is written a bit smaller than the character in front.

So I think that's enough for the first lesson. Please let me know if you're learning with me, if that was alright or if I should change something.
I really hope I can upload those lessons regularly.
Stay safe xx
