On August 22, a major Japanese shipping company Mitsui O.S.K. Lines, an ocean-going cruise liner 
Nippon Maru, can be 
toured free of charge. The photo shows a photo taken by Yurikamome-san while anchored at Harumi Wharf.
Nippon Maru has a total tonnage of 21,903 tons, a hull length of about 160 m, and a passenger capacity of 600. There is only a cruise liner called a "moving hotel", and not only the facilities on board but also the reception of the staff who respond is close to Concierge, a leading hotel. In the story you explained,
１） The cruise fee includes meals, but now a quiz on how many meals 
are offered a day? If you calculate a light meal before breakfast, breakfast, tea and sweets service
, lunch, afternoon tea
, dinner, and then dinner, you can enjoy the meal nine times.
２） If you eat too much, there is an athletic facility on board. Don't worry.
３） There is also a pool, and it seems that hotels in the city center are moving.
４） A quiz about what is piled up in a lifeboat for emergency removal. In addition to food and water, what! It is said that fishing gear 
is also installed as equipment.
５） There is a casino on board, where you can enjoy blackjack and roulette. However, cash cannot be redeemed for cash. You will get a prize. It's a bit like Las Vegas.
Well, I'd like to take a leisurely vacation and enjoy a cruise. For more information about "Nippon Maru", please visit http://www.nipponmaru.jp/.
