2012, Kanbayashi Yasushi, Dokushū konpyūta kagaku kiso III keisan kōgō, translation of Discrete Structures, Logic, and Computability by James L. Hein, page 172:
なぜならグーゴル番目の桁までπを計算した人はいないからある。
Naze nara gūgoru-banme no keta made pai o keisan shita hito wa inai kara aru.
This is because no person has calculated π to the googol-th digit.
2020, Hijikata Nami, Nisen sanjū-nen subete ga kasoku suru sekai ni sonae yo, translation of The Future is Faster Than You Think by Peter Diamandis and Steven Kotler:
Shikashi tatta 100 ko no amino-san de dekita (hikakuteki kogata no) tanpaku-shitsu de mo, sono tori uru kōzō wa 1 gūgoru no 3 jō (1 no ato ni 0 ga 300 ko tsuzuku) aru.
But even a (relatively small) protein comprising only 100 amino acids has one googol cubed (1 followed by 300 zeroes) possible structures.
2021 October 1, “Uchū de kongo ‘1 googol-nen’ inai ni okoru koto ga yaba sugiru [What happens in space within ‘1 googol years’ is too crazy]”, in Creators[1], archived from the original on 10-1-2021:
Konkai wa “ima kara 1-gūgoru-nen inai ni jissai ni uchū de okoru koto” o tēma ni kiji o o-okurishite-ikimasu. Mazu １-gūgoru to iu no wa su no tanni de, １-gūgoru = 10 ˄ 100 desu. １ no ato ni ０ ga １００ ko tsuku, tondemonaku kyodai na su to iu koto ni narimasu.
The theme of our story this time is “What actually happens in space within 1 googol years”. First, googol is a number unit, and 1 googol = 10100. That is an unbelievably large number: 1 followed by one hundred zeroes.
