Tashika, ashita no kaigi wa gogo ni-ji kara datta to omoimasu.

If I remember correctly, I think tomorrow's meeting starts at 2 PM.

Tashikana jōhō ga erareru made, kono ken ni tsuite no hatsugen wa hikaemashō.

Let's refrain from making statements about this matter until we obtain reliable information.

Kare wa wakai keredo, ryōri no ude wa tashika da.

He is young, but his cooking skills are highly reliable.

Sono jiken ga okita no wa, tashika san-nen mae no fuyu datta.

If I remember correctly, it was the winter of three years ago when that incident occurred.

Tashikana shōko ga nai kagiri, kare o hannin da to utagau beki dewa nai.

Unless there is certain evidence, we should not suspect him of being the culprit.

Ano hito no namae wa, tashika Satō-san datta to kioku shite imasu.

I recall that person's name was, if I'm not mistaken, Mr. Sato.
