Sad to say this trip did not turn out as what we planned and expected. On the day of our arrival at Chitose Airport we had to spend more than 7 hours waiting at the airport due to the late arrival of one of my brothers-in-law from Shanghai, China. He was also the first person to fall sick due to the cold weather. Then my sister-in-law, aged 83, was the second person to be affected by the weather. A few days before the end of our stay in Japan, the wife of one of my brothers-in-law became seriously ill and has to be hospitalised, until today. We wished her speedy recovery.
