Lan lives next door to longtime friend Mayl Sakurai (Maylu Sakurai in the English anime, Meiru Sakurai in the Japanese versions).

He is also friends with Dex Ogreon (Dekao Oyama) and Yai Ayano (Yaito Ayanokouji), and in the anime, also becomes friends with Tory Froid (Tohru Hikawa) early on in the series.
How Lan obtained MegaMan is unknown in the games - they were long acquainted from the beginning. In the anime, however, Lan was the operator for a generic Navi, eagerly awaiting the day that his father - who was often away on business trips - would send him his own custom-made Navi. When MegaMan presented himself to Lan, he was visibly underwhelmed until he saw MegaMan in action, defeating Dex and GutsMan with ease.
Throughout all of the Battle Network games, Lan enjoys a rivalry with top NetBattler Eugene Chaud (Chaud Blaze in the English anime and manga, Enzan Ijuuin in the Japanese version), just as MegaMan enjoys a rivalry with Chaud's NetNavi, ProtoMan (Blues).
In Mega Man Battle Network 3, he makes a friend, Mamoru. It is revealed that Mamoru has the same illness that Lan's brother Hub did, but he survived due to surgery. Lan and MegaMan had to beat PlantMan.EXE to save Mamoru.

This responsibility leads Lan on many missions involving the Darkloids and the Dark Chips in Axess, and his duties are expanded in Stream, as he becomes one of the Cross Fusion members opposing Duo.
Lan actually makes a cameo appearance of sorts in Mega Man Star Force 2. From having a Battle Network game in the DS' second slot, player character, Geo Stelar, can collect pieces of Lan's diary which chronicle events after the Battle Network series, and even reveal that Lan himself hypothesized the concept of "Link Power" that is a main focus in the game and an integral part of the world of Star Force (which takes place roughly 200 years after Battle Network), and Geo receives an email from Lan himself, which thanks him for finding his diary, states that Lan wrote it because he wanted to leave some kind of message to the people of the future, and asking how is it in the future, and ending with "we will work harder to make a happy future!"
Lan is a typical carefree, happy Go-lucky youth in search of adventure and fun. He frequently NetBattles, and places the prospect of completing menial tasks like homework behind him. Despite his seemingly carefree attitude, Lan is always prompt to do the right thing, either for the world, or simply for a friend. In another typical case of youthful protagonist personality is that in all versions of him, he remains oblivious of Maylu's feelings for him. Though his personality is mostly the same in all three mediums, he expresses much more aggressive and disobedient tendencies in the manga, often getting into fist-fights or ditching classes.
He is talented on inline skates in every version of the franchise, loves curry in the anime and manga, and commonly decorates his room with soccer-themes in the games(though this apparent affinity is never mentioned or elaborated on). Throughout each series Lan becomes more mature through each series. Lan's favorite color is blue, his favorite fruit is ripe mango, his favorite toothpaste is strawberry-scented, and he despises cockroaches and the sound of fingernails on a chalkboard. In the English version, he hates the sound of an alarm clock instead. In the games, the manga, and the anime not only does he have the same personatlity through them all, He has the same care for Maylu all the same. Lan's favorite hobbies are sleeping, netbattling and his main priority FOOD!
