Your paternal lineage may be linked to many of the Massim groups of Papua New Guinea

Haplogroup O2a is prevalent among Massim ethnic groups, including the populations of Airara, Nomanby, the eastern tip of the mainland, the Trobriand Islands, Gawa, Woodlark, the Laughland Islands, and western Calvados. While Papua New Guinea has been inhabited for over 50,000 years, the Massim may have arrived in the last 2,000 years. Today, these populations remain connected through a traditional island trading system called the Kula Ring. Under this exchange system, residents ensure that goods that are only available on some islands, but that are vitally needed in other islands, are shared among the island populations. Only Massim men participate in the Kula exchange system, and it is common for men to be away from home for months at a time when trading with men from other islands.

Your maternal lineage may be linked to the Han

Members of haplogroup D are found in both northern and southern Han Chinese populations at low to moderate frequencies. The Han people, who all share the same language and similar cultural practices, are the largest ethnic group in the world, with about 1.2 billion people. Historical evidence shows that Han people are descendants of the ancient Huaxia tribes that come from northern China, and Han language and culture only expanded into southern China in the last 2,000 years. The spread of Han people and culture from northern to southern China was likely driven by warfare and famine in the north.

What do people with the surname Saito have in common?

Spoiler alert: it's complicated. People with the same last name are usually no more genetically similar than a randomly sampled group of people from the same population. That said, people with the same surname are more likely to have similar ancestries than randomly sampled individuals. The reason is the tendency of people with similar cultural or geographical backgrounds to preferentially mate with one another. That's why people who share a surname may be more likely to share traits and tendencies in common than people within the general population.
