[Reprint Decided] Over 10,000 Copies Sold in 1 Month! Masanori Kuwana's New Book 'It Was Good to Do! Habit Encyclopedia,' by a YouTuber with over 220,000 Subscribers, Ranks High in Major Bookstores Including Kinokuniya Shinjuku Main Store

Persons Link Co., Ltd. (Representative Director: Masanori Kuwana) is pleased to announce that its new book, 'It Was Good to Do! Habit Encyclopedia: 100 Small Actions That Elevate Your Life' (Publisher: Subarusya), released in March 2026, has surpassed a cumulative total of 10,000 copies sold in approximately one month since its launch.

The book has been widely featured in major bookstores nationwide, including a large-scale display in the trending books section on the 1st floor of Kinokuniya Shinjuku Main Store and prominent shelf placement in various Yurindo stores, leading to an unprecedentedly fast decision for a reprint.

**■ "You don't have to try too hard" captures the hearts of young and business professionals who struggle to take the first step.**

Amidst anxieties about an uncertain future and comparisons on social media, many modern individuals feel pressured to "do something" but find it difficult to take that heavy first step. Responding to this mindset, the book, which started with an initial print run of 8,000 copies, received a huge response immediately after its release and has been widely embraced by students, office workers, freelancers, and homemakers aged 10 to 40.

"Extremely easy to read": With 100 habits concisely summarized, it has gained support from those who are not avid readers, who say, "I can do this."

"No need to blame yourself": The tone, which doesn't contrast with "amazing people" but rather suggests starting as you are, deeply resonates with those who harbor anxiety.

The structure, which emphasizes "time performance" (Taipa) with Masanori Kuwana's proposed "Habit Encyclopedia in 3 minutes, alphabetical order," led to overwhelming support, with readers feeling, "I can do this too."
