  • Last year I just barely missed the Three-Star Buffet, so I came again this year! There were oysters, abalone, shrimp, turban shells, scallops, and crab piled up in their shells, and you can steam them in a bamboo steamer and enjoy as much as you like. All-you-can-eat crab even in summer made me so happy… it was packed with flavor and absolutely amazing! The sashimi selection had also been upgraded—fatty salmon, red sea bream, fresh tuna, and more. Everything was fresh and delicious! I was also glad that Häagen-Dazs is now available at breakfast too! It gets crowded toward the end of the meal, so I recommend grabbing plenty around the middle. Around the middle of dinner service, they take a photo for you with your smartphone. The free alcohol and soft drinks available during the day were still included as well—much appreciated. Table tennis was fun too! The only slight disappointment was that karaoke used to be free until 7 p.m., but now it’s paid all day (550 yen per person per hour). Still, we booked it and enjoyed karaoke anyway—it turned into another great trip this year! Thank you for taking such good care of us.
