There is no need to learn to learn "Kanji" (logograms) to learn how to speak Japanese. You can easily learn to communicate in Japanese by pronouncing the "Romanji" (Latin alphabet) spellings of Japanese words that you can learn from any number of Romanji English<->Japanese dictionaries, plus by having a basic knowledge of simplified Japanese grammar.
But when really learning to speak Japanese without resorting to Kanji spellings you really must first learn by heart both the appearance and sounds of the 50+ characters Hiragana character set. By making that effort you will begin your study of Japanese just as every Japanese schoolchild does in their very first year of school. And must learn it completely before they will be allowed to leave first grade.
For study use, the 50+ Hiragana characters are arranged in a 5X10 table. The first row of the Hiragana table are the characters for the five Japanese vowel sounds -- (English A, I, U, E, O) -- in that order. The next and each subsequent row of the table is headed by the unvoiced consonants (English K,S,T,N,H,M,Y,H,W, and N,) in that order.
In the body of the table each cell in a consonant's row shows the Hiragana character for the combined sound of the row's consonant and the column's vowel; that is, in reading across consonant "K"'s row of the table and down sequentially from each character in the vowel row the Hiragana character for that consonant+vowel combination will be "ka", "ki", "ku", "ke", "ko". That character/sound pattern continues for every consonant that heads the table's consonant rows.
This basic 5X10 Hiragana table of the unvoiced consonants can be supplemented by adding the sounds of the voiced consonants "K" (gah), "S" (zah), "T" (da ), "H1" (ba) and "H2" (pa), respectively in the appropriate rows.
The sounds of the Hiragana consonant-vowel table are the basic sounds of spoken Japanese. It is the spoken Japanese language which in most cases can be simply viewed as being an easily spoken series of consonant-vowel utterances ending with a verb. A wall chart is the best way to view and learn the contents of a Hiragana table.
If you find that pin-up/poster style Hiragana wall charts are difficult to find, you can see and order one from Amazon.com. Under the category "Home and Kitchen", search term "Hiragana chart"you will find a Hiragana chart that's printed on inexpensive pillow cases!
Be assured that if you master the Hiragana table you will be able to pronounce simple Japanese words and put them into sentences equally as well as any Japanese first-grade student can.
And do that without, in addition, having to learn "Kanji" characters.
