I'd say that's OK if you know how to I.D. plants and avoid certain disasters but I'm a bit surprised you would do this in Japan given your remarks on pressure on nature from tourism. I have not seen it as you have but have seen Chinese tourism which seems relentless . I can think in many situations it might be a very good thing.But otherwise I remember Gerard Manley Hopkins saying the following:
Gerard Manley Hopkins (1844–89). Poems. 1918.
19. Binsey Poplars
MY aspens dear, whose airy cages quelled,
Quelled or quenched in leaves the leaping sun,
All felled, felled, are all felled;
Of a fresh and following folded rank
Not spared, not one 5
That dandled a sandalled
Shadow that swam or sank
On meadow and river and wind-wandering weed-winding bank.
O if we but knew what we do
When we delve or hew— 10
Hack and rack the growing green!
Since country is so tender
To touch, her being só slender,
That, like this sleek and seeing ball
But a pr**ck will make no eye at all, 15
Where we, even where we mean
To mend her we end her,
When we hew or delve:
After-comers cannot guess the beauty been.
Ten or twelve, only ten or twelve 20
Strokes of havoc únselve
The sweet especial scene,
Rural scene, a rural scene,
Sweet especial rural scene.
