Hachikō is known in Japanese as ‘Faithful Dog Hachikō’, Hachi meaning ‘Eight’ and Kō meaning ‘Affection’.
Loyalty is devotion and faithfulness to a cause, country, group, or person.
No one can serve two masters. Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and Mammon. Jesus, Gospel of Matthew 6:24
Loyalty is the most important and frequently emphasized virtue in Bushido. It combines other six virtues, such as Righteousness (義 Gi), Courage (勇 Yū), Benevolence, (仁 Jin), Respect (礼 Rei), Sincerity (誠 Makoto) and Honour (名誉 Meiyo).
