Metal fittings are used as decorative purpose in shrines and temples of Nikko. For example, Yomei-mon Gate of Toshogu Shrine is well known. Size and shape are not always the same, but these are called Kazari-kanagu (Decorative metal fittings)

An expert makes and repairs the Kazari-kanagu. The expert is called Kazarishi. Mr. Shigenobu Suzuki (1925-) is one of the few Kazarishi in Japan. He started learning when he was 14 years old. After that, Mr. Suzuki has handled production and fixation of Kazari-kanagu in the nation wide.

All work is handmade and it is told that "20 years learning is required for only Nanako." The Nanako is the generic name of small round ditches, which are put around the outstanding point of Kazari-kanagu by equal arrangement. He uses a tool called Tagane. Mr. Suzuki stops breathing when he carves one by one because he needs very careful attention. By the way, the Tagane also is handmade.
"It is not a craftsman if he cannot make his own tool." Mr. Suzuki stressed.

The Kazarishi will be allowed to start working on patterns such as hollyhocks (Family crest of Tokugawa) and Karakusa-moyou (Roughly mean Japanese style Arabesque design) after 20 years working on the Nanako only. Moreover, five additional years will be required to be independent.

"Have I ever been satisfied with my work? Never ever. Because something is wrong always. " Mr. Suzuki continued. However, his contribution was recognized by the government and he was awarded Oujuhoushou prize in 1991.

"I was born in Nikko, and will die in Nikko after all. I leave Toshogu to the generation of posterity, and I will continue my job for that, until I die." He concluded.

There are 5 followers of Mr. Suzuki including his son. His grandchild has been becoming a follower of Mr. Suzuki. Three generations of Mr. Suzuki's family work for Kazari-kanagu.
