An homage to the Hitchhiker's Guide to the Galaxy, a novel with a cult following that extends just a little into Japan.

誰も信じるな is as close as you can get to the phrase “trust no man” in Japanese, though no gender is specified.

The first two characters mean everyone or anyone but change to “no one” with the addition of a negative verb.

The third through fifth characters express the idea of believing in, placing trust in, confiding in, or having faith in.

The last character makes the sentence negative (without the last character, this would mean “trust everyone,” with that last character, it's “trust no one”).

なんくるないさ or Nankurunaisa means “Everything will be all right” and/or “It will all work out one way or another.”

なんくるないさ is an Okinawan (琉球 / Ryūkyū Islands) word written in Japanese.

You might see this romanized with breaks like nankurunai-sa or nankuru-nai-sa. It's the same word either way. However, there is a separate word, なんくるない, in there which is nankurunai, translated as “Don't worry, be happy.” The “sa” or さ part indicates an assertion or interjection.

靈氣療法肇祖臼井甕男先生遺訓招福の秘法萬病の霊薬今日丈けは心配すな感謝して業を励げめ人に親切に is an alternate version of the precepts or tenets of Reiki by Usui Mikao.

It is impossible to be sure which version or versions were actually written by Usui Mikao. This is the less common of the three versions that you might see in the wild.

Here is a breakdown of the characters and a rough translation:
靈氣 療法 肇祖 臼井甕男。
Reiki therapy founder Mikao Usui
先生 遺訓。
Teacher's testament 招福の秘法,　萬病の霊薬。
Invite blessings of [the] secret method, 10,000 illnesses of spiritual medicine.
今日丈けは: 怒るな, 心配すな,　感謝して,　業をはげめ,　人に親切に。
At least for today: Do not be angry, do not worry, be grateful, work with diligence, [and] be kind to people.

These are the “Five Reflections” of Vice Admiral Hajime Matsushita of the Japanese Imperial Navy.

These days, the Five Reflections are recited or contemplated daily by Japan Maritime Self-Defense Force recruits in training. This long proverb is popularly translated into English this way:

Hast thou not gone against sincerity?
Hast thou not felt ashamed of thy words and deeds?
Hast thou not lacked vigor?
Hast thou not exerted all possible efforts?
Hast thou not become slothful?

These are the precepts of Reiki that are attributed to Usui Mikao.
