According to MLIT, even an item listed as allowed may not be carried on board if the airline or security inspector determines that it can be used as a weapon due to its material, strength, shape, etc. Replicas and similar items of restricted items are also restricted.
Some airlines have stricter rules. On international flights, rules of other countries' authorities may also apply.
