    The name ‘Castella Cake’ is ‘Kasutera’ in Japanese. In katakana, it is カステラ. It’s actually not a Japanese word. Thus, it doesn’t exactly sound Japanese. Moreover, that’s because the name comes from the Portuguese phrase “Pão de Castela” which means “bread from Castille”.

    Castille is an old kingdom that belonged to Spain. It was a large and powerful state on the Iberian Peninsula during the Middle Ages. In English translation, it means ‘Castle’. So, basically one of the origins of the name Castella is Castilla, which is the Portuguese name for the Old Kingdom of Casitlla.



    In the 16th century, the Portuguese reached Japan and soon started trade and missionary work. Nagasaki was the only Japanese port open for foreign trade. The Portuguese introduced many unusual things that time, such as guns, tobacco, and pumpkins. It was popular with sailors since they could bring the cake for long periods of time before going off. Moreover, during the Edo period the cake is very popular. However, it is also expensive to buy because of the cost of sugar. So, it was considered quite a luxury item. Over the years, it was changed to suit Japanese taste.

    If you’re wondering on how they bake during the Edo period. The “kiln” used to bake castella in the Edo period. Basically, it has the same mechanism as the current oven. The upper and lower part heats inside the kiln. However, the heat source is charcoal, and the atmosphere is quite different from the current one.



    Nagasaki is an attractively port city on the island of Kyushu and the capital of Nagasaki Prefecture. As one of Japan’s closest port cities to the Asian mainland, Nagasaki has played a prominent role in foreign trade relations for many centuries and was the most important of only a very few ports open to restricted numbers of foreign traders during Japan’s period of isolation.

    Additionally, if you want to travel to Nagasaki, you can reach by taking a train. Take the JR Tokaido/Sanyo Shinkansen from Tokyo to Fukuoka’s Hakata Station and transfer to the JR Kamome limited express train to Nagasaki. There are also flights from Tokyo to Nagasaki Airport. If you want a cheaper route by air, book a flight to Fukuoka airport. From Fukuoka Airport, buses depart to Nagasaki every hour. The one way trip from Fukuoka Airport to Nagasaki takes 2.5 hours and costs 2620 yen. It’s actually cheaper than flying directly into Nagasaki Airport.
