I know we in the West have this notion that Japan is super high tech and futuristic, but that isn't entirely true. Many Japanese people in fact have a mentality of "if it's not broken, don't replace it." Also, older folks in Japan are just as likely to be less tech savvy as anywhere else.
If you were to walk into the typical Japanese office you'd see plenty of modern computers for obvious reasons, but you'd also find plenty of copiers and fax machines and other tech that might seem like they're straight out of the 80s. Walk around and try to spot people using their phones and you will see many people still use flip phones.
The process of modernizing is a slow one in Japan. It's not that they aren't fascinated with new technology, but they also aren't especially quick to add it to their lives unless it's pretty revolutionary in its usefulness. They have one foot rooted in progress and one in tradition.
