Ihai- The tablet made of wood (usually in a shape similiar to a tombstone) created once a family member passes away, the ihai bears the name of the deceased. It is usually something that is kept in a shelf (called a butsudan) and not carried around, as it was believed to carry the soul of the deceased whose name is written on it.
Daruma- Because darumas have no limbs "being like a daruma" means you can't do anything (because you can't move using your limbs). Although darumas have their "good luck on your endeavor" meaning (by filling one eye of the beginning of the endeavor and filling in the other eye at the completion.) That meaning is not used in this instance.
Shuriken- Most people think that "Shuriken" (commonly translated as "ninja stars") come only in that 4-pointed (or multi-pointed) star shape (and hence the common translation most likely.) However, back in the days, shuriken come in all shapes and sizes to suit the users' needs.
kan- An old Japanese unit. 1 kan~ 3.75 kg (~8.25 lbs)
