Can Australians go to Japan without a visa?

Yes, Australian passport holders can travel to Japan without a visa under the Visa Exemption Scheme, provided their stay is for short-term purposes including tourism, business meetings, or visiting family and friends for up to 90 days. If you do not meet these eligibility conditions, you will need to apply for a visa that suits the purpose and duration of your travel to Japan. 

As entry requirements for Japan may change over time, so make sure to verify visa requirements with the Japanese Embassy in Australia, your local Japanese consulate or the Ministry of Foreign Affairs of Japan.
