Seasonal foods are preferred by Japanese people. Crops can be grown earlier in some warmer areas and these can then be shipped across the country. Colder areas harvest the same crops later and can ship these to warmer areas.
Did I mention we have already eaten fresh corn on the cob? Doesn't that suika (watermelon) look good? What is that other fruit? It is called a biwa which is a loquat. It is delicious. It has a nice firm texture and tastes like a combination of different fruits such as apple, peach and others.
