Claim
Izu has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 16 members.
Correction

Izu City's council no longer has 16 seats. The official city council overview says the current council size is 14 members.

Full reasoning

The claim is outdated. Izu City's official council overview page, updated April 4, 2025, states under "議員の任期、定数等" that the city council's 定数 (fixed number of seats) is 14人 for the current term beginning November 1, 2024. The same page also says "議員14名" belong to the standing committees. That directly contradicts the article's statement that the unicameral city legislature has 16 members.

Claim
Hope, British Columbia, Canada, since August 18, 2005
Correction

The Hope sister-city date is wrong. Izu City's official sister-city page gives the Hope agreement date as August 22, 2005, not August 18, 2005.

Full reasoning

Izu City's official Sister City Introduction page lists the partnership date for Hope, British Columbia as 2005年(平成17年)8月22日. On the same page, Nelson is listed with the August 18, 2005 date. The article appears to have repeated Nelson's date for Hope, but the official city source gives Hope's date as August 22, 2005.

Claim
Minamiminowa, Nagano, Japan, since February 25, 1991
Correction

Minamiminowa is not an Izu City sister city. Official records say the old sister-city tie was between Minamiminowa and former Toi town, and it ended after Toi merged into Izu City.

Full reasoning

This entry appears to carry forward a former Toi town relationship as if it were still an Izu City sister city. Izu City's current official sister-city page lists only Nelson and Hope in British Columbia. It does not list Minamiminowa. More importantly, official Minamiminowa village records say that the village had a sister-city partnership with Toi town beginning in February 1991, but that after the Heisei-era municipal mergers, when Toi became part of Izu City, the sister-city arrangement was dissolved. That contradicts the article's claim that Minamiminowa has been a sister city of Izu City since 1991.

Claim
Both towns merged and city settled
Correction

Izu City was not created by merging two towns. Official city sources say it was formed in 2004 by the merger of four towns: Shuzenji, Toi, Amagiyugashima, and Nakaizu.

Full reasoning

This infobox line is incorrect because Izu City was established through a four-town merger, not a merger of only two towns. Izu City's official history page states that the city was born in 2004 through the merger of Shuzenji, Toi, Amagiyugashima, and Nakaizu. Another official city page likewise says Izu City was created when four towns merged on April 1, 2004.
