Thats right, in Japan alone might I add. Over 6m copies of the Youkai Watch games were sold last year more then doubling any other franchise (to be fair I only compared Pokemon and MonHun)
Here are Japans top selling games of 2014 (Youkai Watch in BOLD)
| Title | Maker | System | Release Date | Estimated 2014 sales | Estimated sales to date |
|---|---|---|---|---|---|
| Yo-kai Watch 2 Ganso/Honke | Level-5 | 3DS | 2014/07/10 | 3,050,178 | 3,050,178 |
| Pokémon Omega Ruby & Alpha Sapphire | Pokémon | 3DS | 2014/11/21 | 2,464,850 | 2,464,850 |
| Monster Hunter 4G | CAPCOM | 3DS | 2014/10/11 | 2,381,177 | 2,381,177 |
| Super Smash Bros. for Nintendo 3DS | Nintendo | 3DS | 2014/09/13 | 2,066,022 | 2,066,022 |
| Yo-kai Watch 2: Shinuchi | Level-5 | 3DS | 2014/12/13 | 2,007,327 | 2,007,327 |
| Yo-kai Watch | Level-5 | 3DS | 2013/07/11 | 994,346 | 1,280,799 |
| Mario Kart 8 | Nintendo | Wii U | 2014/05/29 | 842,053 | 842,053 |
| Dragon Quest Monsters 2: Iru & Luca's Wonderful Mysterious Keys | Square Enix | 3DS | 2014/02/06 | 748,139 | 748,139 |
| Kirby Triple Deluxe | Nintendo | 3DS | 2014/01/11 | 687,957 | 687,957 |
| Super Smash Bros. for Wii U | Nintendo | Wii U | 2014/12/06 | 478,366 | 478,366 |
Considering how new Shinuchi is having only been out for less then 3 weeks total in 2014 and still topping charts we can expect to see its sales to continue strongly into 2015 and who knows, maybe it will make the top 10 2 years running.
