For the Tokyoite with a hobby that is hampered by the size of his or her home, there would appear to be a passable solution — simply practice it on the pavement outside the apartment.
A procedure that not only pleases the person whose place it is, but also pedestrians who periodically pass by.
Along with those in search of a soothing sit down.
And yet while particularly packed fish tanks placed in public aren’t exactly what one would term as typical, what’s arguably much more amazing is that after an obliviously long time left totally unattended, they haven’t even been touched,
let alone trashed.
