The official Japanese sources reviewed here clearly address import control treatment for stun guns but do not clearly state the rule for an ordinary domestic purchase in Japan.
buy a taser
Official Japanese sources reviewed do not use the brand term Taser in a way that cleanly answers civilian purchase, carrying or possession; the closest official material found is the Minor Offenses Act on concealed dangerous instruments and Japan Customs material classifying stun guns as weapons.
Compare this activity in other countries
This makes the rule page useful for comparison without creating a second data source.
Australia
Australia does not have one uniform civilian pepper-spray rule. Victoria Police says capsicum spray is illegal to purchase, possess, carry or use without a Governor in Council exemption or Chief Commissioner approval, while WA regulations expressly allow carrying or possessing a capsicum spray weapon for lawful defence where the person has reasonable grounds to apprehend circumstances may arise.
Austria
Austria’s official pepper spray page allows civilian pepper spray but says it may only be used exclusively in self-defence. Carrying it therefore depends on lawful adult possession and self-defence use.
Belgium
Belgian Justice lists self-defence aerosols and sprays as prohibited weapons. Prohibited weapons cannot lawfully be possessed, bought, transported or carried by civilians.
Canada
Sprays designed for use against people are prohibited weapons in Canada but animal repellent sprays are treated differently if they are genuinely for animal control.
