I travelled and entered Singapore from Japan a few days ago. There wasn't much formalities I had to carry out except that I had to filled up the online SG Health Declaration form. From the Japan side, I did not have to do anything prior to departure.
On arrival at SG Changi Airport, the immigration officer checked my passport and did an iris and facial scan. I was also reminded of the do's and don'ts during my 2 weeks Stay-Home-Notice at a dedicated facility.
Next, I collected my luggage, cleared customs and was guided to a bus with half dozen other arrival passengers to our hotel.
All these whiles, we had to wear our face masks and refrain from talking or asking the bus driver which hotel we will be staying.
On arrival at our hotel where we will be spending our next 2 weeks in quarantine, we were greeted by the hotel staff and ushered to a small room next to the reception and briefed about our laundry, meals etc.
A few days before the end of the quarantined period, we would be told where to go for our swab test. We had to prepay the swab test of $186 per person online. We were told to book our taxis through the hotel and we have to bear the transportation cost. The hotel which we are staying for the next 2 weeks are paid for by the SG government.
Finally, after receiving the result of the swab tests and if "negative" we will check out of the hotel and go back to our home.
