The international sea passenger transport receipts in Japan are projected to decline steadily from 2024 to 2028, with values dropping from 3.7 billion Euros in 2024 to 2.1 billion Euros in 2028. This represents an annual average decrease of approximately 13% over the five-year period, indicating significant diminishing revenue in this sector. In 2023, receipts were at 4.1 billion Euros, marking the beginning of a downward trend observed in recent forecasts.

Future trends to watch for include:

The impact of economic conditions on international sea travel demand.
Potential shifts in tourism patterns and preferences.
Environmental regulations affecting shipping and passenger vessel operations.
Technological advancements that could alter the cost and efficiency of sea travel.
