Ashtray on Wheels
If you’re a frequent Japanese smoker, you’re almost certain to have one of them in your hands at any given time. Japan has invented an alternative to the increasingly damaging and wasteful practice of just burying one’s ashes in the ground, and they have done it in an environmentally friendly manner.
If a police officer approaches you while you are smoking in Japan, do not be alarmed. This is common in the country. You are not at any risk of being detained or arrested at this time. An alternative will be offered to you in the form of an environmentally friendly heat-resistant reusable bag in which to deposit your ashes. When you’re done, just rinse it out and it will be ready for the next time you need it.
