How to Imitate Names

There are two ways to imitate names. These are:
Generational suffix (Yamato: 世代間の接尾辞 sedaikan-no-setsubiji)
Description: Determines the generational position of the individual of the same name as his or her parents. For example:
Senior/I (〜１世 -Issei): The default generational suffix of the original holder of the name. For unisex names, the name can be passed down to either sex.
Junior/II (〜２世 -Nisei): Indicates a child of the name's original holder.
III (〜３世 -Sansei): Indicates a grandchild of the name's original holder.
IV (〜４世 -Yonsei): Indicates a child of III.
V (〜５世 -Gosei): Indicates a child of IV.
VI (〜６世 -Rokusei): Indicates a child of V.
VII (〜７世 -Nana/Shissei): Indicates a child of VI.
VIII (〜８世 -Hassei): Indicates a child of VII.
IX (〜９世 -Kusei): Indicates a child of VIII.
X (〜１０世 -(Ichi)jūsei): Indicates a child of IX.
L (〜５０世 Gojūsei): Indicates a child of XLIX.
C (〜１００世 -Hyaku/Ippyakusei): Indicates a child of XCIX.
D (〜５００世 -Gohyakusei): Indicates a child of CDXCIX.
M (〜１０００世 -(Is)sensei): Indicates a child of CMXCIX.
V̄ (〜５０００世 -Gosensei): Indicates a child of MV̄CMXCIX.
X̄ (〜１００００世 -Ichimansei): Indicates a child of MX̄CMXCIX.
L̄ (〜５００００世 -Gosensei): Indicates a child of X̄L̄MX̄CMXCIX.
C̄ (〜１０００００世 -(Ichi)jūmansei): Indicates a child of X̄C̄MX̄CMXCIX.
D̄ (〜５０００００世 -Gojūmansei): Indicates a child of C̄D̄X̄C̄MX̄CMXCIX.
M̄ (〜１００００００世 -Hyaku/Ippyakumansei): Indicates a child of C̄M̄X̄C̄MX̄CMXCIX.
M̄̄ (〜１０００００００００世 -(Ichi)jūokusei): Indicates a child of C̄̄M̄̄X̄̄C̄̄M̄X̄̄C̄M̄X̄C̄MX̄CMXCIX.
M̄̄̄ (〜１００００００００００００世 -(It)chōsei): Indicates a child of C̄̄̄M̄̄̄X̄̄̄C̄̄̄M̄̄X̄̄̄C̄̄M̄̄X̄̄C̄̄M̄X̄̄C̄M̄X̄C̄MX̄CMXCIX.
Sibling number (同胞数 dōhōsū)
Description: This suffix is to distinguish more than one sibling of the same generational suffix. This number always succeeds the generational suffix and is based upon the individual's birth order, so #1 (〜１号 -Ichigo) is for first borns only.

How to Copy Names

If you want to name your children after yourself or any one of your ancestors, consider the following terms: Name suffix (Yamato: 名接尾辞 meisetsubiji):
These suffixes are usually used after the parent's real name; for example:
I or Senior (〜壹世 -Issei): Refers to the original holder of the name.
II or Junior (〜貳世 -Nisei): Refers to one of the children of the original holder of the name.
III (〜参世 -Sansei): Refers to one of the grandchildren of the name's original holder.
IV (〜肆世 -Shi-/Yonsei): Refers to one of the great-grandchildren of the preceeding name's original holder.
V (〜伍世 -Gosei): Refers to one of the second great-grandchildren of the name's original carrier.
X (〜(壹)拾世 -(Ichi-)jūsei): Refers to one of the seventh great-grandchildren of the original carrier of the name.
L (〜伍拾世 -Gojūsei): Refers to one of the forty-seventh great-grandchildren of the name's original owner.
C (〜(壹)佰世 -(Ip-)p/hyakusei): Refers to one of the ninety-seventh great-grandchildren of the original owner of the name.
D (〜伍佰世 -Gohyakusei): Refers to one of the 497th great-grandchildren of the name's original possessor.
M (〜(壹)阡世 -(Is-)sensei): Refers to one of the 997th great-grandchildren of the original possessor of the name.
These suffixes also apply to pseudonyms.
Name number (名数 meisū):
These go after the generational suffix to signify the child's birth order. Id est:
#1 (〜壹号 -Ichigō): Refers to the eldest child to possess a generational suffix, which means that it only refers to the eldest child in the family if all the children should go by a generational suffix. Subsequent siblings get higher numbers to distinguish their names from that of the eldest sibling.
