Every port of call on a Japan cruise is worth a visit, as each has its own unique flavour and sights to see.
If you visit Tokyo (from Yokohama), you won't miss Mount Fuji, Japan's highest peak. This mountain is actually an active volcano, and dominates the skyline from over a hundred kilometres away. Within the city itself is the Imperial Palace, surrounded by parks, walls and moats. The palace is closed to the public, but the grounds are beautiful, particularly in the spring when the blossoms bloom.
Hiroshima's recent past is known all over the world, so a visit to the Hiroshima Peace Memorial Park is the perfect place to pay respects. Other than monuments and memorials, there's also a museum and several buildings left standing as a reminder of that fateful day.
We also recommend the Golden Pavilion and Nijo Castle in Kyoto, Fukuoka Castle and Canal City Hakata in Fukuoka, and Ninja-dera Temple and the famous seafood of Kanazawa.
