The name of the village, Vailoa-uta, is derived from the Samoan language and translates into English as “Long River Inland".

[14] The village and the district became a proponent of this government (mālō) as can be seen in the old Samoan parable, the War between Tuveve and Sātele.

[19] The HTC Tuā'olo, of the Ma'opūtasi district, is the protector of the salutation, Faleagafulu (the ten houses of Tutuila); this was a gift Queen Salamāsina gave to the Tui Manu’a during her installation as Samoa's first Tafa'ifā (holder of the four pāpā titles).

The Manu'a king would then bestow the title upon the HTC to thank PC Mauga for his hospitality during a visit to Tutuila on his return trip home.

[20] The raising of the U.S. flag over Tutuila saw the end of Ātua's influence over the island, much to the relief of local chiefs who were tired of the endless wars in 'Upolu.

LMS missionaries note that an elaborate feast marked the special occasion with attendance by dignitaries and family members from around the island.

[32] In May 1968, the government radio station WVUV-AM moved from Utulei and began operations at its new quarters in Vailoatai, next to Leone High School.

South Seas Broadcasting, Inc. bought what was left of the station, and in 2008, opened WVUV-FM at the Aitūlagi Building office complex in Tafuna.

[37][38] The village regularly participates in the Flag Day's cricket (men's and women's) games and fautasi (traditional Samoan long boat) races.

[43] A forceful blow was applied to the back of the head, or tuāulu, using a traditional heavy war club like the talavalu.

Sunia notes that the title goes back as far as 500 A.D., and that the Tuife'ai of that time is responsible for the first failed invasion of the Manu'a kingdom.

[45] The title established familial ties with the Mālietoa in the 13th or 14th century and was later renamed Tuisāmoa of the Poutasi village, Falealīlī.

[55][56] King I’amafana and his forces returned to 'Upolu, and the village took the words ‘aso tau’ (Day of War) as the name of its malae to commemorate the event.
