Legal answer
Possess a pepper spray in a car in Japan: legal status
Official Japanese sources clearly prohibit concealing and carrying a dangerous instrument without justifiable reason, and official customs materials classify tear-gas aerosol spray as a weapon for tariff purposes, but I did not find a clean official rule here that directly answers ordinary civilian ownership or simple home or vehicle possession of pepper spray.

Conditions
What would need to be true
If carried concealed in a way that fits the Minor Offenses Act, liability can arise without justifiable reason.
Exceptions
Known carve-outs
No clean official civilian self-defence exception for ordinary possession was identified in the sources reviewed.
Penalties
Possible enforcement risk
The official materials cited do not cleanly state a penalty for this exact pepper-spray activity; concealed carrying of a dangerous instrument without justifiable reason is punishable under the Minor Offenses Act.
Enforcement
How this is usually enforced
Police enforcement can arise if the item is carried concealed without justifiable reason or otherwise used in crime; item-specific civilian possession treatment still needs direct official confirmation.
