Strength in Japanese, when used for a tattoo is usually written in Kanji. If you have not studied Japanese, you may not be aware that there are three Japanese alphabets. These are called hiragana, katakana and kanji. Although it is possible to write the word strength in all of the alphabets, most people will choose to write it in Kanji. Kanji is usually used for concepts and Katakana is usually used for Names and foreign words. Kanji is the word in Japanese that is used to refer to chinese characters. These characters were originally simplified from characters brought to Japan from China.
Some of the other Japanese symbols that are always popular for tattoos are also related to the strength or power theme. These include spirit, warrior, courage and bravery. If you have looked at all of the Japanese symbols related to family and still can't decide, then you could always go for a universally popular character, the character for Peace. In Japanese the word for Peace is 'Heiwa'. It is a great choice if you are looking for a symbol with a powerful yet simple meaning in one character. ( By Emily Kato )
