The term '24 hours' in this context does not refer to working hours. According to Japanese regulations, students are generally allowed to work part-time for a maximum of 28 hours per week during study periods (approximately 4 hours per day), and 40 hours per week (8 hours per day) during long school holidays.

The essential tasks that new students must complete within the first 24 hours (or the first few days) upon arrival in Japan are related to legal registration and settling in.

🛂 At the Airport (Within 24 Hours of Arrival)

These critical steps are completed at the Japanese airport's immigration counter (e.g., Narita, Haneda, Kansai, etc.) upon entry:

• Obtain the Residence Card (Zairyū Card): Get your Residence Card (Zairyū Card), which includes the visa stamp, from Immigration. This card is your primary identification document in Japan and must be carried with you at all times.
• Obtain Permission to Engage in Activity Other Than That Permitted by the Status of Residence (Work Permit): To legally work part-time on a student visa, you must apply for and receive the "Permission to Engage in Activity Other Than That Permitted" right at the airport's Immigration desk. This permit is stamped on the back of your Residence Card. If you fail to obtain this permit, you cannot legally work in Japan.

🏘️ Legal Procedures (Within 14 Days of Arrival)

After reaching your place of residence (Hostel/Apartment) from the airport:

• Register at the Municipality Office (Residency Registration): Within 14 days of entering Japan, you must take your Residence Card to the Municipality Office (City Hall or Ward Office) where you live and register your address. This is called Residency Registration (Jūmin tōroku).
• Register for Health Insurance: While registering your residency, you must also register for the National Health Insurance (Kokumin Kenkō Hoken). This is mandatory and significantly reduces the cost of medical treatment.

🏫 Other Important Settlement Tasks

• Report to School/College: Immediately report to your college or language school to confirm your attendance and complete any necessary enrollment procedures.
• Open a Bank Account: Open a Bank Account to manage daily expenses and receive your part-time job salary.
• Communication Setup: Arrange for a SIM Card or Pocket Wi-Fi to ensure easy communication and internet access for your stay in Japan.

⚠️ Important Information Regarding Part-Time Work

To clarify the '24 hours' context regarding work:

• Legal Limit: Student visa holders in Japan are legally restricted to working a maximum of 28 hours per week.
• During Long Breaks: During long school holidays (such as summer vacation), the limit is temporarily increased to 40 hours per week (or 8 hours per day).

Exceeding this legal work limit may result in the non-renewal or cancellation of your student visa. It is mandatory to prioritize your studies and strictly adhere to these regulations.
