Is it worth spending 7 days in Nagoya?

This summer family trip to Japan lasted for 7 days. Day 1: Shanghai-Nagoya. After arriving in the evening, we had a very famous pork chop rice [Misokatsu Yabaton Yaba-cho Honten 矢場とん 矢場町本店]. The pork chop was delicious. Since we lived near the Sakae shopping district, we went to the Chubu Electric Power MIRAI TOWER after dinner. The next day: a day trip to Ghibli Park. The park is very big, so we went around until about 4 o'clock and then went back. The big warehouse had an appointment for 11 o'clock. We went around for about 4 hours and bought a lot of souvenirs... For dinner, we went to the local delicious chicken wings [Mountain of the World]. We went there for 2 consecutive days. There is a branch near the Rong business district. I still miss it! Day 3: One-day trip to Kamikochi. It took about 3 and a half hours by bus from Nagoya. The bus stopped at Taisho Pond. It took us about 2 hours to walk to Kappa Bridge. We took some photos near the Kappa Bridge to replenish our energy! Day 4: One-day trip to Takayama and Shirakawa-go, about 2 hours by bus. I went to the morning market in Takayama and ate Hida beef. Then I went to Shirakawa-go at noon. Hahahaha, when the weather is good, Shirakawa-go is really hot 🥵. You can get tanned into charcoal directly. Everyone should wear sunscreen! On the way back, we stopped at Nagoya Station and walked to the Michelin-starred restaurant [Shishimaru Noodle House Lion Ball]. They put a lot of MSG in it. I drank a bottle of water at night! Day 5: Legoland Japan, suitable for children under 10 years old, but it is great for taking photos, and there is also a small aquarium at the entrance! I went to see the night view of Nagoya at night. I bought a ticket at [Midland Square] opposite Nagoya Station to go up to the 42nd floor, and then went to the 46th floor to see the night view. Day 6: I slept until I woke up naturally in the morning, queued up for a drink at [Kato Coffee Shop Ei Store] and waited for a full 90 minutes, then went to the Nagoya Science Museum, which I personally think is very suitable for children, great! After that, we went to the famous Unafuji Shirakabe Bettei. It was really expensive. Four people ate for 1200, hahaha, but the eel was really good. Day 7: I slept until I woke up naturally, took an amphibious bus from Sakae to Nagoya Port, and then drove on the water for 20 minutes. After the drive, I went to Nagoya Castle, which was more spectacular than Osaka Castle! After finishing, I went to Nagoya Station to buy [ECHIRE] but the taste was just so-so. Later, I went to Starbucks Coffee - Nagoya JR Gate Tower. This Starbucks is really good and has an open-air terrace! Compared to Osaka, Nagoya has fewer people. Here I recommend a Nishihara coffee shop, which is very good. You must check it out when you go to Nagoya~ In short, you must go to the restaurants I recommend. They are all delicious foods that you won’t regret eating.
