It's sensible, but how is it Zen? In what way does it partake of the Buddha nature? :-)
Or a Moleskine.
You know ... Zen. The kind of brands the Dalai Lama would consume if he were a rich SF hipster. Zen.
The other two cases are not as open and shut.
Basho, who brought haiku into its modern form, was not a monk, but did practice Zen meditation as a layman, and lived as a pilgrim and hermit, teaching a circle of disciples, like an abbot. Issa, the second most influential haiku poet after Basho, was an honest-to-goodness Jodo Shinshu Buddhist (though not Zen!) priest. Furthermore, the haiku aesthetic embodies Zen's fierce focus on the ephemeral beauty of the current moment. I think that saying that the practice of haiku is "influenced by the same principles" is such an understatement as to be absurd.
Right now I am not going to dig into the history of raku.
Zen is a school of buddhism which focuses on enlightenment, with different sub schools that focus on different methods for attaining enlightenment (well actually it's not, but it helps seeing Zen practitioners goal as gaining enlightment). Zen is not rock gardens, wabi sabi or haikus. Christianity is not building gothic cathedrals.
Glad I have no clue about Zen, or I would need to slap you on your head with a stick.
Of course Zen does not consist of composing haiku, building rock gardens, or reading koans.
... dropping the trivial words makes the tagline weird. It's "Zen Judaism: For You, A Little Enlightenment".
