The Arabic says 'Juhood' - which means 'to do one's utmost to try with all one's power'. It is from the root word 'Jahd' and from which you also get 'ijtihad' (to make an independent legal or theological judgement based on interpretation); 'mujtahid' (Islamic legist) and a whole host of other words.
The Japanese calligraphy is an adaptation of a piece by Miyamoto Musashi (c.1584-1645) who was a famous martial artist, warrior, painter, sculptor and philosopher. He is believed to have been one of the most skilled swordsmen in the history of Japan. Musahsi was notorious for defeating the best of swordsmen by simply using a bokken (wooden sword) or at times even a whittled down oar! He also invented and developed the Hyoho Niten Ichi-ryu style of swordsmanship (using two swords as one) and wrote Go Rin No Sho, The Book of Five Rings, (see Thinker's Corner) an enigmatic book of strategy, tactics, and philosophy that is much studied by business people and others even today.
Both pieces of calligraphy together depict 'The Spirit of Struggle'
