The pilotage fees in Japan are computed by a uniform formula. The tariff prescribed by the Regulations for the Enforcement of the Pilotage Law incorporates the basic rates and additional rates. The basic rate applies to vessels with gross tonnage 1,000 tons or below having a loaded draught 3 meters or below, whereas the additional rate applies to vessels with gross tonnage greater than the forementioned in such a manner that additional fees are computed for every 1,000 tons of tonnage exceeding 1,000 tons gross and for every 30 centimeters of draught exceeding 3 meters.
　　　　　The above calculation method can be expressed by the following formula:

　　　A + B ((GRT - 1,000)/1,000 + (D - 3.00)/0.3)
　　　where
　　　　　A : basic rate
　　　　　B : additional rate
　　　　　GRT : gross tonnage
　　　　　D : deepest draught in meters

　　　　　The basic rate (A) and additional rate (B) can, in principle, be calculated by the formula below except for those waters requiring extremely skilled maneuvering arts (unit Yen):
　　　･Pilotage fee for entering/leaving port or shifting
　　　　　A = 32,000 + 2,010 (d - 3)
　　　　　B = 1,190 + 75(d - 3)
　　　･Mileage fee other than that for entering/leaving port or shifting
　　　　　A' = 2,010 d
　　　　　B' = 75 d
　　　[Note]
　　　　　A: Count \50 and over up to \99 as \100 and disregard \49 and smaller.
　　　　　d : Pilotage distance (nautical miles)


Non-Power-Driven Vessels
　　　　　For piloting a non-power-driven ship, an 80% of extra fee is charged on top of the regular pilotage fee.

Dual Pilotage
　　　　　When a vessel is served by two pilots, fees for such dual pilotage services are computed on the basis of the modified rate(*) against the prescribed rates being applied to each one of the pilots in a team except for a vessel with her wheelhouse located on one side of the vessel where the full rate is applied to each pilot.
　　　Note : *
　　　　　compulsory pilotage areas : 75%
　　　　　non-compulsory pilotage areas : 85%

Trial Trip
　　　　　For pilotage services rendered during trial trip, adjustment of compass and calibration of radio direction finder, the rates for entering port operation of vessels are applied.
　　　　　When such services exceed two hours, a 50% of extra fee is added for each hour or fraction thereof after the first two-hour period.

Night Extra Charge
　　　　　For pilotage services at nighttime, a 50% of extra fee is charged on top of the regular rates.

Multi-Decker Extra Charge
　　　　　For pilotage services rendered to multi-decked ships, an extra fee is charged. The rate is calculated by the following formula:
　　　　　B (or B') x ((3.5/1,000) x L3 - 1.2 x GRT)/1,000
　　　　　L : Length overall.

Winter Extra Charge
　　　　　For pilotage service during winter season (December - March) in northern pilotage districts, 10 〜 40% of daytime fee is charged on top of the regular pilotage fee.

Detention
　　　　　For any detention caused to a pilot or his boat already despatched, which is exceeding 30 minutes period with respect to the designated time of commencement of pilotage service \5,400 of waiting charge is billed for each additional hour of detention or fraction thereof.
