Japanese Navy magazines can be fitted to any fuze that takes a standard Navy gaine. Magazines are used to initiate low explosives such as black powder and are never used in a high explosive filled bomb.

There are two types of magazines. The type 98 Mk 6 bomb magazine Model 2 is instan-taneous. The type 98 Mk 6 bomb magazine Model 1 incorporates a 0.03 second delay. The "a" and "b" plugs are similar to those used in standard gaines. The "d" plugs contain a large amount of gun-powder.
