Before getting started, let me introduce some basic information on Japanese language. There are 2 types of basic components of Japanese writing system, which are Kana and Kanji.
Kanji is adopted from logographic Chinese characters that are used in modern Japanese writing system along with Hiragana, Katakana, Hindu-Arabic numerals and the occasional use of the Latin alphabets. The Japanese term writing kanji for the Chinese characters literally means "Han characters" and is written using the same characters as the Chinese word hanzi.
Kana is a pair of syllabaries, consisting of Hiragana and Katakana. Hiragana is used along with Kanji for native or neutralized Japanese words and for grammatical elements. Katakana is used for foreign words and names, loanwords, onomatopoeia, scientific names, and sometimes to replace Kanji or Hiragana for emphasis.
Thie images provided were the characters in Kana. I found that these images were interesting and easy to learn. Such a good start for dummies like me. I don't own these images. Credits to the owner.
