Peter Magoshiro Matsuoka was appointed to succeed him, and supervised Yamashita Sekkei in the construction of the modern new cathedral to meet the growning demand of the community.

Upon the completion of the concrete Gothic revival cathedral and the elevation of the prefecture to diocese in 1962, Matsuoka was consecrated as its first bishop.

Tall spires rise 50 meters above the ground over twin belfries on either side of the cathedral, and serve as a visual reference point around the Aoi neighborhood.

[2][3] The diocese formerly operated the Nunoike Foreign Language College on the cathedral grounds for 36 years until its closure in 2023.

[5] Masses are held in many languages, including English and Tagalog, catering to the expatriate community in Nagoya.
