I went during the weekdays, and I think I cover most of the stuffs I wanted to check without express card.

Do take note that there'll be an extra charge of 1000 Yen tax for departure from Japan starting January 7th.

Visitors to Japan will have to pay a 1,000 yen (S$12.50) levy when leaving the country from Monday, Japanese media reported.

Japan will start collecting the 1,000 yen departure tax for each person leaving the country by aircraft or ship regardless of nationality, the Japan Times reported on Tuesday.

Under the relevant law, which was enacted in April last year, the levy will be collected each time an individual leaves the country, and comes on top of airfare, ship fare and travel fees.

People leaving Japan within 24 hours of their transit entry and children under two years old will be exempted from the departure tax, the report said. Those with tickets purchased and issued before Jan 7 will also be exempted, it added.

Specifically, the revenue will be used to set up facial recognition gates at airports for speedier immigration procedures, while also promoting the use of multilingual information boards and helping to introduce more cashless payment terminals for public transportation.

I also bought from Klook. But I used their WiFi dongle during my stay there, unlimited data until I return the device in KL. Also they manage to help me with securing last minute device because I forgot to book earlier.
