No visa required for entry to Japan. Stays of up to 90 days are permitted under the visa-waiver agreement.
You're travelling to Japan (JP). Your home cellular plan may or may not include data abroad — check your carrier's international options before you fly. An eSIM is a low-commitment alternative if your plan doesn't cover the destination or charges high roaming rates.
Japan (JP) screens applicants and arriving travellers against criminal records (landing permission). If your history is clean, no action — proceed normally. If you've ever been convicted of anything, two things matter: (1) any visa or entry-permit application asks the question, and answering 'no' when the answer is 'yes' is itself grounds for refusal even if the original conviction wouldn't have been; (2) some categories trigger denial regardless — the canonical examples are DUI for Canada and drug-related convictions for Japan. Research waivers / rehabilitation routes well before booking if either applies to you.

Japan (JP) restricts or bans the import of: stimulants (amphetamine-based ADHD medication like Adderall), pseudoephedrine (some cold medicines), codeine above certain quantities. The risk is real — travellers have been detained at customs for over-the-counter products that are routine elsewhere. If you take any prescription medication, look up the active ingredient against the restricted list above before booking. Always carry the prescription bottle plus a doctor's letter naming the medication and the condition it treats. Adding your medications to your profile (optional) lets us tell you specifically which of yours match. Japan bans most stimulant medications including Adderall, Vyvanse, Dexedrine.
