Japanese shipowners are pushing Tokyo for fundamental reforms in the country's tonnage tax system. This request includes opening the system directly to shipowners and reducing reliance on tonnage under the Japanese flag.
Reform Priorities for Fiscal Year 2027
The president of the Japan Shipowners' Association, Hitoshi Nagasawa, who is also the president of Nippon Yusen Kaisha (NYK), emphasized that these changes have been presented as a priority request for the 2027 tax reforms. The current tonnage tax system will continue until the end of the fiscal year 2027, but the association has addressed this request ahead of time, as the scale of the desired changes requires legal reforms.
Challenges Facing Reforms
Nagasawa stated that the current regime imposes conditions such as the Japanese flag and other requirements that do not exist in many competing international tonnage tax systems. This has placed local shipping interests at a disadvantage. The association is calling for an expansion of this plan from the current focus on operators to shipowners, as well as changes to the requirements for the Japanese flag. Additionally, the association is seeking improvements in tax exemptions for registration and exemptions from property tax for qualifying ships.
Implementing these reforms may face challenges. Motonari Adachi, the director-general of the Maritime Bureau at the Ministry of Land, Infrastructure, Transport and Tourism of Japan, described the extension of the tonnage tax to shipowners as the biggest element of the industry's request — but this sector also faces the toughest opposition from tax authorities.
Reports indicate that Tokyo is preparing to review four main tax measures in the shipping industry as a package and is increasingly framing financial support for the fleet as an economic security issue.
