2. Osamu Kusakabe (Kyōtango, Kyoto pr.) (n. 10 de fevereiro de 1914),
Is Osamu Kusakabe still alive? I didn't find any news about him
Kiyotaka Mizuno was the 8th oldest man in Japan, and now just 8 months later he may be the 1st, Japan is rapidly losing its oldest men
Seiyoshi Shigematsu (Matsuyama, Ehime pr.) (b. 28 December 1914)
Does anyone have news about Seiyoshi Shigematsu?, was he taken from the oldest living men in Japan on the grg wiki, but I couldn't find a source of his death, or did he go to limbo?

LongeviQuest is pleased to announce that, in collaboration with the Ministry of Health, Labor and Welfare (MHLW), we have identified Japan’s new oldest living man. Verified by the MHLW in August, the 110-year-old Tokyo resident assumed the title following the passing of Tomisaburō Wakui on 5 July 2024.
The gentleman, whose name has been withheld for privacy reasons, was born on 23 January 1914, making him 110 years and 226 days old as of 5 September 2024. He is less than two months younger than the previous titleholder, Wakui.
LongeviQuest validated his age on 2 September. Currently, he is the fifth-oldest (validated) living man in the world, according to the LongeviQuest Atlas.

Kiyotaka Mizuno (Japanese: 水野清隆), a resident of Iwata in Shizuoka Prefecture, has been recognized as Japan’s new oldest living man, at the age of 110 years, 183 days.
Kiyotaka Mizuno was born in Iwata, Shizuoka Prefecture, Japan, on 14 March 1914. In his youth, he reportedly served as a guard for the Emperor and served on the continent during World War II, narrowly escaping death before returning to Iwata.
After the war, he worked as a farmer, producing shrimp potatoes and white leeks, until his 80s. At the age of 108, he lived at home with his eldest son and his family, and was able to eat and bathe on his own.
Today, on the 13th, Mayor Hiroaki Kusachi visited Mizuno at his home to present him with a bouquet of flowers in honor of his remarkable longevity.
It was reported that Mizuno assumed the title of Japan’s oldest living man in late August, following the passing of an anonymous man from Tokyo, born on January 23, 1914. LongeviQuest is awaiting confirmation of the exact date of his passing.

Overduidelijk misschien.
The GRG wiki includes this man named Sigezo Kono. Is he actually a real person because I don't see any proof that this man exists?
@billy-robinson His name is spelled wrong, it's Shigezō Kōno, as Marco reported here.
@musicotic ok I didn't realise he was included in the list for September last year. How come they don't include him here then? Is he in limbo?
Kōki Kamozaki entered the list on September 5, 2024.
Since March 14, 2025, we have 7 110+ on this list (three lists during this period). The previous list had only six.
Fukuoka leaves the list, replaced by Hiroshima, which had not appeared since November 3, 2022, with Shigeru Nakamura (#1 at the time).

https://longeviquest.com/2025/10/ryoji-shinoda-balanced-japanese-meals-longevity/
LongeviQuest recently had the privilege of speaking with the family of Mr. Ryōji Shinoda (篠田錂治) of Osaka, whose balanced Japanese meals and longevity reflect a lifetime of discipline and care. He is now 110 and will celebrate his 111th birthday this November. Through their stories, we learned about his healthy lifestyle, which he maintained while living independently until the age of 110 years and 10 months—centered around balanced Japanese meals and daily habits that reflected his lifelong sense of discipline.
Ryōji Shinoda was born in Gifu Prefecture, Japan, on 30 November 1914. He worked for many years at an electric power company, where he was known for his diligence and precision. After retirement, he continued to lead an active life, enjoying golf until around the age of 88.
In his early 90s, after his wife suffered a bone fracture, the couple moved into a nursing home together. When Shinoda was 99 years old, his wife passed away, after which he made the remarkable decision to leave the facility and return to his own home, where he began living alone once again with the support of housekeepers.
By the time he reached 110, Shinoda had already lost sight in one eye and had very limited vision in the other, yet he continued to live independently with the help of housekeepers, caregivers, and nearby relatives. Known for his strict and orderly personality, he maintained a precise daily routine and continued to manage his life with discipline.
He did not nap during the day, moving around his home on his own and then sitting in his chair to listen to television programs—especially baseball broadcasts. Even as his eyesight declined, he continued using a computer with the aid of a screen magnifier until around the age of 109.
Shinoda personally oversaw the preparation of his meals, giving detailed instructions to ensure they were balanced and nutritious, incorporating a Japanese-style approach that emphasized variety and moderation. His breakfast and lunch were gentle on the stomach, consisting of light and easily digestible foods suitable for his age. Breakfast typically included rice porridge with pickles such as takuan or senmaizuke, sweet miso paste, and Caspian Sea yogurt topped with a small amount of fruit. Lunch was usually a lighter meal of bread or noodles, with a serving of assorted fruit and tea.
Dinner was the meal he cared most about, and he always made sure to include beans—usually simmered beans—along with half a pack of natto. His meals also featured simmered vegetable dishes, as well as vinegared dishes made with ingredients such as yam, cucumber, daikon, wakame seaweed, or shirasu (whitebait), which varied from day to day. He regularly enjoyed grilled salmon, shumai dumplings, broccoli and tomato, small side dishes of seasonal greens such as ohitashi or sesame dressing, and red miso soup with wakame, tofu, or fried tofu.
His dinners featured a wide variety of nutritious ingredients—including vegetables, beans, fish, and eggs—served in modest portions that reflected his balanced approach to eating. Rather than having a single main dish, his meals followed the Japanese principle of ichiju-tasai—one soup accompanied by many small dishes—allowing him to enjoy both balance and variety. He preferred this style of eating throughout his later years, instructing his housekeepers to prepare his meals in this way as part of his health-conscious approach to daily life.
In September 2023, Shinoda was recognized as the oldest living man in Osaka Prefecture. He lived independently at home until the age of 110 years and 10 months. After a fall in late September 2025, he was hospitalized and continues to receive care, having since recovered from his injuries.
