On 11 March 2011, the Tōhoku earthquake and tsunami occurred during the location of "Sand no Bonyarinu TV" at Kesennuma, which hit his partner Mikio Date and the programme staff. Although he took refuge at Azumi Mountain by the staff's instructions, a fire broke out after the town was flooded by the tsunami, and it became in a state where they could not go down the mountain. After that, they evacuated to a hotel lobby in Kesennuma. The next morning he reported on his blog that they were safe, and while he was headed for Tohoku Broadcasting, he was live on "Hiroshi Kume Radio nandesukedo". After arriving at Tohoku Broadcasting, he went to his parents house and confirmed the safety of his relatives. It took him ten hours to return to Tokyo. Furthermore, the comment column of Tomizawa's blog is open as a communication bulletin board of safety information.
