On April 29, 1973, “Othello,” a nationally popular board game, was released.
The trademark “Othello,” which designates “board games” as the goods covered, is a registered trademark of Othello Co., Ltd. Incidentally, “Reversi” is now in the public domain. (p)

As we entered 2026, announcements regarding the discontinuation of Blu-ray drive sales began to pour in from various companies.

Notice Regarding the Discontinuation of Blu-ray Drive Sales | Buffalo (Japanese only)
Announcement of end of our external Blu-ray drive sale | ELECOM CO., LTD. ELECOM
Notice Regarding the Discontinuation of External Blu-ray Drive Sales and Support – Logitec INA Solutions Co., Ltd. (Japanese only)

Regarding recorders, TVS REGZA and Sony have made similar announcements, and Pioneer has already withdrawn from the optical disc business.

The Blu-ray Disc standard was announced in 2002. The terms “Blu-ray,” “BLU-RAY DISC,” and related logos were trademarked by the Blu-ray Disc Association as early as 2001. The year 2006, when consumer products first appeared, was dubbed the “Year One of Blu-ray.”

While I feel there are still situations where Blu-ray is needed, the fact that it is heading toward its end without a complete generational shift from DVD seems to be due to the spread of video streaming services and the rise of HDDs, SSDs, and cloud storage as the mainstream storage methods, leading to a decline in demand for Blu-ray, which is at a disadvantage in terms of capacity and cost.
I sometimes purchase Blu-ray discs for video content I want to keep on hand. There used to be a sense of joy in owning them, but it seems there are quite a few users who rarely have the opportunity to use them.

On the other hand, I-O Data and Verbatim Japan have announced plans to continue supplying Blu-ray drives and discs.

While Blu-ray won’t become unusable anytime soon, if you need to store data long-term or keep backups on hand, you may need to reconsider your storage methods. (Syszo)

　The other day, I purchased an incense burner and an offering cup at the “Hasegawa Buddhist Altars” store located in a shopping mall. They are made of Noritake bone china, and when I looked at the back, I saw the logos of both Hasegawa and Noritake.

　The design next to the “Hasegawa” text (Japanese Trademark Registration No. 5557659) and the Noritake logo are both registered trademarks. While Noritake has several registered logos, the oldest one was registered in 1963! (Japanese Trademark Registration No. 631574)

　We don’t have a Buddhist altar at home, but I really love this Noritake cup. It blends well with our interior decor, and despite its small size, it’s just as beautiful as a standard-sized cup. It allows me to easily place an offering and pray, so I’m very fond of it.

　At Hasegawa, in response to changing lifestyles, they offer a variety of products designed to make “moments of prayer” more accessible. In addition to Noritake Buddhist altar ware, these include living room altars created in collaboration with “Karimoku Furniture” in Kariya City, Aichi Prefecture, and the “Oshidan” (fave altar), where you can enshrine your fave. The “Oshidan” was apparently conceived by a company employee, is trademarked (Japanese Trademark Registration No. 6776045), and was even available at the store I visited. (Marron)
